Description

[0001] The present invention relates to novel pyrazole compounds and their use as T-type calcium channel blockers in the treatment or prevention of various diseases or disorders where calcium T channels are involved, to pharmaceutical compositions containing these derivatives, and to processes for their preparation.

[0002] Intracellular calcium concentrations control important life processes such as signal transduction pathways, hormones and neurotransmitter release, muscular contraction, gene expression and cell division. Control of calcium influx across the cellular membrane is in part regulated by a family of transmembrane proteins termed voltage-gated calcium channels (VOCs). They are activated by changes in electrical potential difference across the membrane and have been further classified into different subtypes based on biophysical and pharmacological considerations: Cav1.x (L-type for Long-lasting), Cav2.x (N-, P / Q- and R-types; N for Neuronal, P for Purkinje cells, Q (after P) and R for Remaining or Resistant) and Cav3.x (T-type for Transient). The L, N, P and Q-type channels activate at more positive potentials (high voltage activated) and display diverse kinetics and voltage-dependent properties. The T-type class (or "low voltage-activated") is characterized by fast inactivation (transient) and small conductance (tiny) and is composed of three members due to the different main pore-forming α1 subunits: Cav3.1 (α1 G), Cav3.2 (α1 H) and Cav3.3 (α1 I).

[0003] Nearly all "excitable" cells, such as neurons of the central nervous system (CNS), peripheral nerve cells and muscle cells, including those of skeletal muscles, cardiac muscles, and venous and arterial smooth muscles, have voltage-dependent calcium channels. In consequence, calcium T channels have been linked to various human diseases and disorders, such as especially epilepsy, pain, neuropathic pain, sleep disorders, sleep disturbances, schizophrenia, essential tremors, Parkinson's disease, neurodegenerative disorders, depression, anxiety, psychosis, autism, drug addiction, hypertension, cardiac arrhythmias, heart block, cancer, diabetes, infertility and sexual dysfunction (Bourinet, E.; Alloui, A.; Monteil, A.; Barrere, C.; Couette, B.; Poirot, O.; Pages, A.; McRory, J.; Snutch, T. P.; Eschalier, A.; Nargeot, J., EMBO J 2005, 24 (2), 315-324; Flatters, S.J.L., Drugs Fut. 2005, 30(6), 573-580 ; Giordanetto, F.; Knerr, L.; Wallberg, A., Expert Opin Ther Pat 2011, 21 (1), 85-101; Huguenard, J.

D.; Drott, J. M.; Uebele, V. N.; Renger, J. J.; Lee, A.; Li, Z.; Le, A. D.; Hutson, P. H., Biol Psychiatry 2010, 68 (8), 712-8; Wildburger, N. C.; Lin-Ye, A.; Baird, M. A.; Lei, D.; Bao, J., Mol Neurodegener 2009, 4, 44).

[0004] In the brain, T-type calcium channels are essential for regulating neuronal excitability and burst firing, both in the central and peripheral nervous system (Lambert, R. C.; Bessaih, T.; Crunelli, V.; Leresche, N., Pflugers Arch 2014, 466 (3), 415-23.). They are linked to diseases or disorders where abnormal oscillatory activity occurs in the brain, as well as diseases or disorders where there is abnormal coupling of activity, particular through the thalamus. They are particularly linked to an increasing number of neurological disorders such as the epilepsy disorders and neuropathic pain.

[0005] T-type calcium channels play a role in regulating neuronal firing patterns under normal physiological conditions, such as during sleep rhythms (Anderson, M. P.; Mochizuki, T.; Xie, J.; Fischler, W.; Manger, J. P.; Talley, E. M.; Scammell, T. E.; Tonegawa, S., Proc Natl Acad Sci U S A 2005, 102 (5), 1743-8; Destexhe, A.; Contreras, D.; Sejnowski, T. J.; Steriade, M., J Neurophysiol 1994, 72 (2), 803-18; Lee, J.; Kim, D.; Shin, H. S., Proc Natl Acad Sci U S A 2004, 101 (52), 18195-9; Steriade, M., Trends Neurosci 2005, 28 (6), 317-24.). However, T-type calcium channels are also involved in pathophysiological conditions such as epilepsy, autism, hypertension, atrial fibrillation, congenital heart failure, pain, psychoses and cancer (for review, see Iftinca, M. C., J Med Life 2011, 4 (2), 126-38).

[0006] T-type calcium channels are critical players in the development of idiopathic generalized seizures in humans and animals (Cheong, E.; Shin, H. S., Pflugers Arch 2014, 466 (4), 719-34; Khosravani, H.; Zamponi, G. W., Physiol Rev 2006, 86 (3), 941-66; Zamponi, G. W.; Lory, P.; Perez-Reyes, E., Pflugers Arch 2010, 460 (2), 395-403). In animals, knockout of Cav3.1 calcium channels protects mice from absence seizures (Kim, D.; Song, I.; Keum, S.; Lee, T.; Jeong, M. J.; Kim, S. S.; McEnery, M. W.; Shin, H. S., Neuron 2001, 31 (1), 35-45; Song, I.; Kim, D.; Choi, S.; Sun, M.; Kim, Y.; Shin, H. S., J Neurosci 2004, 24 (22), 5249-57). In rat models of absence epilepsy (GAERS or WAG / Rij), a gain of function mutation of the Cav3.2 gene has been reported (Powell, K. L.; Cain, S. M.; Ng, C.; Sirdesai, S.; David, L. S.; Kyi, M.; Garcia, E.; Tyson, J. R.; Reid, C. A.; Bahlo, M.; Foote, S. J.; Snutch, T. P.; O'Brien, T. J., J Neurosci 2009, 29 (2), 371-80), as well as elevated levels of Cav3.1 and Cav3.2 mRNA and an increase in the amplitude of the T-type calcium current in comparison to normal rat strain (Broicher, T.; Kanyshkova, T.; Meuth, P.; Pape, H. C.; Budde, T., Mol Cell Neurosci 2008, 39 (3), 384-99; Talley, E. M.; Solorzano, G.; Depaulis, A.; Perez-Reyes, E.; Bayliss, D. A., Brain Res Mol Brain Res 2000, 75 (1), 159-65; Tsakiridou, E.; Bertollini, L.; de Curtis, M.; Avanzini, G.; Pape, H. C., J Neurosci 1995, 15 (4), 3110-7; Powell, K. L.; Cain, S. M.; Ng, C.; Sirdesai, S.; David, L. S.; Kyi, M.; Garcia, E.; Tyson, J. R.; Reid, C. A.; Bahlo, M.; Foote, S. J.; Snutch, T. P.; O'Brien, T. J., J Neurosci 2009, 29 (2), 371-80). In human, number of mutations have been described in Cav3.2 channels in patients with childhood absence and other forms of idiopathic generalized epilepsies (Heron, S. E.; Khosravani, H.; Varela, D.; Bladen, C.; Williams, T. C.; Newman, M. R.; Scheffer, I. E.; Berkovic, S. F.; Mulley, J. C.; Zamponi, G. W., Ann Neurol 2007, 62 (6), 560-8; Khosravani, H.; Zamponi, G. W., Physiol Rev 2006, 86 (3), 941-66; Zamponi, G. W.; Lory, P.; Perez-Reyes, E., Pflugers Arch 2010, 460 (2), 395-403). Those mutations are predicted to cause a gain of function with increase in calcium current, or can trigger an alteration of the balance between excitatory and inhibitory neuronal elements. As direct consequence, it may result in an increased spiking behavior in neurons that exhibit this rebound bursting, thereby contributing to the generation of epileptiform discharges.

[0007] In another type of epilepsy, i.e. the temporal lobe epilepsy, it has been shown in the pilocarpine rodent model that T-type calcium currents were uppregulated after status epilepticus and suggest a role of this channel in long-lasting modification of neuronal firing mode (regular to burst firing) and potential contribution to the development and expression of an epileptic condition after SE (Yaari, Y.; Yue, C.; Su, H., J Physiol 2007, 580 (Pt. 2), 435-50; Becker, A. J.; Pitsch, J.; Sochivko, D.; Opitz, T.; Staniek, M.; Chen, C. C.; Campbell, K. P.; Schoch, S.; Yaari, Y.; Beck, H., J Neurosci 2008, 28 (49), 13341-53; Graef, J. D.; Nordskog, B. K.; Wiggins, W. F.; Godwin, D. W., J Neurosci 2009, 29 (14), 4430-41; Su, H.; Sochivko, D.; Becker, A.; Chen, J.; Jiang, Y.; Yaari, Y.; Beck, H., J Neurosci 2002, 22 (9), 3645-55).

[0008] Increased activity of T-type calcium channel has been associated to neuropathic and inflammatory pain states (for review, see Todorovic, S. M.; Jevtovic-Todorovic, V., Br J Pharmacol 2011, 163 (3), 484-95). When nociceptors are in an increased state of responsiveness, they often respond to normal sensory stimuli as if painful (allodynia) and to mildly painful stimuli as though they were acutely painful (hyperalgesia). The electrophysiological answer of these altered pain responses, include lower thresholds of activation, increased frequency of firing in response to suprathreshold stimuli and spontaneous firing (Coderre, T. J.; Katz, J.; Vaccarino, A. L.; Melzack, R., Pain 1993, 52 (3), 259-85; Bhave, G.; Gereau, R. W. t., J Neurobiol 2004, 61 (1), 88-106). T-type calcium channel are abundantly expressed in nociceptors, spinal dorsal horn and thalamic neurons (Talley, E. M.; Cribbs, L. L.; Lee, J. H.; Daud, A.; Perez-Reyes, E.; Bayliss, D. A., J Neurosci 1999, 19 (6), 1895-911) and increased T-type channel activity has been linked to neuropathic and inflammatory pain states in animals and humans (Jagodic, M. M.; Pathirathna, S.; Nelson, M. T.; Mancuso, S.; Joksovic, P. M.; Rosenberg, E. R.; Bayliss, D. A.; Jevtovic-Todorovic, V.; Todorovic, S. M., J Neurosci 2007, 27 (12), 3305-16; Todorovic, S. M.; Jevtovic-Todorovic, V., Channels (Austin) 2007, 1 (4), 238-45; Jagodic, M. M.; Pathirathna, S.; Joksovic, P. M.; Lee, W.; Nelson, M. T.; Naik, A. K.; Su, P.; Jevtovic-Todorovic, V.; Todorovic, S. M., J Neurophysiol 2008, 99 (6), 3151-6). T-channels may play a role in the decrease of the threshold for action potential firing in dorsal root ganglia (DRG) cells that express T-channels (Nelson, M. T.; Todorovic, S. M.; Perez-Reyes, E., Curr Pharm Des 2006, 12 (18), 2189-97; Jagodic, M. M.; Pathirathna, S.; Nelson, M. T.; Mancuso, S.; Joksovic, P. M.; Rosenberg, E. R.; Bayliss, D. A.; Jevtovic-Todorovic, V.; Todorovic, S. M., J Neurosci 2007, 27 (12), 3305-16). T-type calcium channels would play a role of amplifiers of peripheral pain signals. Pharmacological and molecular downregulation of the function of these channels in DRG neurons supports the notion that T-channels contribute to the chronic pain associated with peripheral axonal injury (Bourinet, E.; Alloui, A.; Monteil, A.; Barrere, C.; Couette, B.; Poirot, O.; Pages, A.; McRory, J.; Snutch, T. P.; Eschalier, A.; Nargeot, J., EMBO J 2005, 24 (2), 315-24; Wen, X. J.; Li, Z. J.; Chen, Z. X.; Fang, Z. Y.; Yang, C. X.; Li, H.; Zeng, Y. M., Acta Pharmacol Sin 2006, 27 (12), 1547-52) (or for review, see (Jevtovic-Todorovic, V.; Todorovic, S. M., Cell Calcium 2006, 40 (2), 197-203)).

[0009] In addition, T-type calcium channel activity is upregulated during diabetic neuropathy (Hall, K. E.; Sima, A. A.; Wiley, J. W., J Physiol 1995, 486 (2), 313-22; Jagodic, M. M.; Pathirathna, S.; Nelson, M. T.; Mancuso, S.; Joksovic, P. M.; Rosenberg, E. R.; Bayliss, D. A.; Jevtovic-Todorovic, V.; Todorovic, S. M., J Neurosci 2007, 27 (12), 3305-16). Selective knock-down of DRG Cav3.2 currents in vivo has effectively reversed mechanical and thermal hyperalgesia in STZ-induced diabetic neuropathy in rats (Messinger, R. B.; Naik, A. K.; Jagodic, M. M.; Nelson, M. T.; Lee, W. Y.; Choe, W. J.; Orestes, P.; Latham, J. R.; Todorovic, S. M.; Jevtovic-Todorovic, V., Pain 2009, 145 (1-2), 184-95). Furthermore, significant up-regulation of Cav3.2 T-channel mRNA in DRG tissue homogenates and concomitant up-regulation of Cav3.2 T-currents in nociceptive DRG cells has been reported in another model of painful diabetic neuropathy, leptin-deficient ob / ob mice (Latham, J. R.; Pathirathna, S.; Jagodic, M. M.; Choe, W. J.; Levin, M. E.; Nelson, M. T.; Lee, W. Y.; Krishnan, K.; Covey, D. F.; Todorovic, S. M.; Jevtovic-Todorovic, V., Diabetes 2009, 58 (11), 2656-65). In humans, extracellular recordings from the medial thalamus of patients with neurogenic pain have shown abnormalities of LTS-mediated bursts that could at least contribute to persistent pain (Jeanmonod, D.; Magnin, M.; Morel, A., Brain 1996, 119 (2), 363-75).

[0010] It has been shown that T-type calcium (Ca) channels in the CNS are closely associated with repetitive burst discharges or neuronal oscillations (Llinas, R.; Yarom, Y., J Physiol 1986, 376, 163-82; Gutnick, M. J.; Yarom, Y., J Neurosci Methods 1989, 28 (1-2), 93-9; Iftinca, M. C.; Zamponi, G. W., Trends Pharmacol Sci 2009, 30 (1), 32-40). Tremor is a common encountered involuntary movements, and it is associated with various neurological diseases or pathological conditions such as essential tremor (ET) and Parkinson's disease (PD) and its related disorders. As tremor-related neuronal activities may be closely related to repetitive or oscillatory activities in the CNS, controlling T-type Ca channels may have therapeutic effects. This hypothesis is supported by neuro-anotomical and functional expression of expression of T-type calcium channels in area involved pathophysiological mechanisms underlying harmaline-induced tremor, a pharmacological model of ET in rodents (Llinas, R.; Yarom, Y., J Physiol 1986, 376, 163-82; Cavelier, P.; Lohof, A. M.; Lonchamp, E.; Beekenkamp, H.; Mariani, J.; Bossu, J. L., Neuroreport 2008, 19 (3), 299-303). Moreover, animal data involving selective knockdown of the Cav3.1 gene or mice lacking the Cav3.1 gene showed that Cav3.1 channels play a specific role in ET (Park, Y. G.; Park, H. Y.; Lee, C. J.; Choi, S.; Jo, S.; Choi, H.; Kim, Y. H.; Shin, H. S.; Llinas, R. R.; Kim, D., Proc Natl Acad Sci USA 2010, 107 (23), 10731-6). On the other hand, the role of the other isoform of the T-type calcium channels (Cav3.2 and Cav 3.3) in this pathology is not known but cannot be excluded (Miwa, H.; Kondo, T., Cerebellum 2011, 10 (3), 563-9).

[0011] In Parkinson's disease (PD) patients, deep brain stimulation of the subthalamic nucleus has been shown to be an effective treatment for parkinsonian symptoms indicating a pivotal role of this area in the pathogenesis of PD: In patients, as well as in animal models of PD, this area seems to have an abnormal pattern of firing with an increase of the burst firing mode. And this burst firig mode has been shown to involve the T-type Ca 2+< channels (for review, see Yang, Y. C.; Tai, C. H.; Pan, M. K.; Kuo, C. C., Pflugers Arch 2014, 466 (4), 747-55).

[0013] The compounds of formula (I) may contain one or more stereogenic or asymmetric centers, such as one or more asymmetric carbon atoms. The compounds of formula (I) may thus be present as mixtures of stereoisomers or preferably as pure stereoisomers. Mixtures of stereoisomers may be separated in a manner known to a person skilled in the art.

[0014] Furthermore, in some instances, the compounds of the present invention may be present in tautomeric forms. Any such tautomeric form is encompassed. For example, it is well understood that, in case a benzimidazole moiety is unsubstituted on the ring nitrogen having a free valency such benzimidazole moiety represents tautomeric forms. Thus, further substituents of the benzimidazole moiety may be attached in the position(s) ortho to the bridgehead atoms (i.e. attached in position(s) 4 and / or 7), and / or in the position(s) meta to the bridgehead atoms, (i.e. attached in position(s) 5 and / or 6). It is understood that the two ortho, and, respectively, the two meta positions are considered equivalent. For example, the group 4-methyl-1H-benzoimidazol-2-yl is understood to signify the same group as 7-methyl-1H-benzoimidazol-2-yl and 4-methyl-3H-benzoimidazol-2-yl and 7-methyl-3H-benzoimidazol-2-yl.

[0015] The present invention also includes isotopically labelled, especially 2< H (deuterium) labelled compounds of formula (I) according to embodiments 1) to 29), which compounds are identical to the compounds of formula (I) except that one or more atoms have each been replaced by an atom having the same atomic number but an atomic mass different from the atomic mass usually found in nature. Isotopically labelled, especially 2< H (deuterium) labelled compounds of formula (I) and salts thereof are within the scope of the present invention. Substitution of hydrogen with the heavier isotope 2< H (deuterium) may lead to greater metabolic stability, resulting e.g. in increased in-vivo half-life or reduced dosage requirements, or may lead to reduced inhibition of cytochrome P450 enzymes, resulting e.g. in an improved safety profile. In one embodiment of the invention, the compounds of formula (I) are not isotopically labelled, or they are labelled only with one or more deuterium atoms. In a sub-embodiment, the compounds of formula (I) are not isotopically labelled at all. Isotopically labelled compounds of formula (I) may be prepared in analogy to the methods described hereinafter, but using the appropriate isotopic variation of suitable reagents or starting materials.

[0016] In this patent application, variably attached bonds may be used for substituents or groups (e.g. (R 4< ) n and (R 5< ) m ) . In such case it is meant that any such substituent or group may be attached to any carbon atom of the ring system to which the variable attached bond is drawn into, provided that said carbon atom is not already substituted.

[0017] In this patent application, a bond drawn as a dotted line shows the point of attachment of the radical drawn. For example, the radical drawn below is a 1H-pyrazol-1,3-diyl group.

[0043] It is to be understood, that a stereogenic center in a compound disclosed above, which stereogenic center is not specifically assigned, may be in absolute (R)- or absolute (S)-configuration; for example a compound listed as N-[1-(5-cyano-pyridin-2-ylmethyl)-1H-pyrazol-3-yl]-2-(3-methyl-chroman-7-yl)-acetamide may be N-[1-(5-cyano-pyridin-2-ylmethyl)-1H-pyrazol-3-yl]-2-((R)-3-methyl-chroman-7-yl)-acetamide, N-[1-(5-cyano-pyridin-2-ylmethyl)-1H-pyrazol-3-yl]-2-((S)-3-methyl-chroman-7-yl)-acetamide or any mixture thereof.

[0044] The compounds of formula (I) according to embodiments 1) to 31) and their pharmaceutically acceptable salts can be used as medicaments, e.g. in the form of pharmaceutical compositions for enteral (such especially oral) or parenteral administration (including topical application or inhalation).

[0045] The production of the pharmaceutical compositions can be effected in a manner which will be familiar to any person skilled in the art (see for example Remington, The Science and Practice of Pharmacy, 21st Edition (2005), Part 5, "Pharmaceutical Manufacturing" [published by Lippincott Williams & Wilkins]) by bringing the described compounds of formula (I), or their pharmaceutically acceptable salts, optionally in combination with other therapeutically valuable substances, into a galenical administration form together with suitable, nontoxic, inert, therapeutically compatible solid or liquid carrier materials and, if desired, usual pharmaceutical adjuvants.

[0046] The present disclosure also relates to a method for the prevention or treatment of a disease or disorder mentioned herein comprising administering to a subject a pharmaceutically active amount of a compound of formula (I) as defined in any one of embodiments 1) to 31).

[0047] In a preferred embodiment of the invention, the administered amount is comprised between 1 mg and 1000 mg per day, particularly between 5 mg and 500 mg per day, more particularly between 25 mg and 400 mg per day, especially between 50 mg and 200 mg per day.

[0048] Whenever the word "between" is used to describe a numerical range, it is to be understood that the end points of the indicated range are explicitly included in the range. For example: if a temperature range is described to be between 40 °C and 80 °C, this means that the end points 40 °C and 80 °C are included in the range; or if a variable is defined as being an integer between 1 and 4, this means that the variable is the integer 1, 2, 3, or 4.

[0049] Unless used regarding temperatures, the term "about" (or alternatively the term "around") placed before a numerical value "X" refers in the current application to an interval extending from X minus 10% of X to X plus 10% of X, and preferably to an interval extending from X minus 5% of X to X plus 5% of X. In the particular case of temperatures, the term "about" placed before a temperature "Y" refers in the current application to an interval extending from the temperature Y minus 10 °C to Y plus 10 °C, and preferably to an interval extending from Y minus 5 °C to Y plus 5 °C.

[0050] For avoidance of any doubt, if compounds are described as useful for the prevention or treatment of certain diseases, such compounds are likewise suitable for use in the preparation of a medicament for the prevention or treatment of said diseases.

[0051] The compounds of formula (I) as defined in any one of embodiments 1) to 31) are useful for the prevention or treatment of diseases or disorders where calcium T channels are involved.

[0052] Such diseases or disorders where calcium T channels are involved may be defined as including especially: epilepsy (notably absence epilepsy, childhood absence and other forms of idiopathic generalized epilepsies, temporal lobe epilepsy); sleep disorders and sleep disturbances; pain (notably inflammatory pain, neuropathic pain, peripheral pain, chronic pain associated with peripheral axonal injury); neurological diseases and disorders (notably essential tremors, Parkinson's disease, schizophrenia, depression, anxiety, psychosis, neurodegenerative disorders, autism, drug addiction); cardiovascular diseases and disorders (notably hypertension, cardiac arrhythmias, atrial fibrillation, congenital heart failure, heart block); cancer; diabetes and diabetic neuropathy; and infertility and sexual dysfunction.

[0053] Notably such diseases or disorders where calcium T channels are involved refer to epilepsy, neurological disorders, and pain. Preferably such diseases or disorders refer to epilepsy and pain.

[0054] The term "epilepsy" describes recurrent unprovoked seizures wherein the term "seizure" refers to an excessive and / or hypersynchronous electrical neuronal activity. Different types of "epilepsy" are disclosed for example in [Berg et al., Epilepsia. 2010; 51(4): 676-685], which reference is herewith incorporated by reference. The term "epilepsy" as used herein preferably refers to absence epilepsy, childhood absence and other forms of idiopathic generalized epilepsies, temporal lobe epilepsy.

[0055] The term "pain" preferably refers to inflammatory pain, neuropathic pain, peripheral pain, and chronic pain associated with peripheral axonal injury.

[0056] The term "neurological diseases and disorders" preferably refers to essential tremors, Parkinson's disease, schizophrenia, depression, anxiety, psychosis, neurodegenerative disorders, autism, drug addiction.

[0057] The term " cardiovascular diseases and disorders " preferably refers to hypertension, cardiac arrhythmias, atrial fibrillation, congenital heart failure, heart block.

[0058] The compounds of formula (I) as defined in embodiments 1) to 31) are also useful in a method of reducing the concentration of calcium in a neuronal cell, and wherein said reduction in calcium is achieved by blocking the calcium T-channel present in such neuronal cell; said method comprising the administration of a compound of formula (I) as defined in embodiments 1) to 31).

[0059] The compounds of formula (I) as defined in embodiments 1) to 31) are also useful in a method of decreasing burst firing discharges in a neuronal cell and wherein said decrease of burst firing is achieved by blocking the calcium T-channel; said method comprising the administration of a compound of formula (I) as defined in embodiments 1) to 31).Preparation of compounds of formula (I):

[0060] The compounds of formula (I) can be prepared by the methods given below, by the methods given in the experimental part below or by analogous methods. Optimum reaction conditions may vary with the particular reactants or solvents used, but such conditions can be determined by a person skilled in the art by routine optimisation procedures. In the schemes below, the generic groups X, Y, R 1< , R 2< , (R 4< ) n , and (R 5< ) m are as defined for the compounds of formula (I). In some instances the generic groups R 1< , R 2< , (R 4< ) n , and (R 5< ) m may be incompatible with the assembly illustrated in the schemes and so will require the use of protecting groups (PG). The use of protecting groups is well known in the art (see for example "Protective Groups in Organic Synthesis", T.W. Greene, P.G.M. Wuts, Wiley-Interscience, 1999). For the purposes of this discussion, it will be assumed that such protecting groups as necessary are in place. In some cases the final product may be further modified, for example, by manipulation of substituents to give a new final product. These manipulations may include, but are not limited to, reduction, oxidation, alkylation, acylation, and hydrolysis reactions which are commonly known to those skilled in the art. The compounds obtained may also be converted into salts, especially pharmaceutically acceptable salts in a manner known per se.

[0061] Compounds of general formula (II) can be prepared via an amide coupling as final step (Scheme 1). Generally, the corresponding carboxylic acid (IV) can be activated to the corresponding acid chloride, typically with oxalyl chloride. Alternatively, the carboxylic acid (IV) can be directly coupled to the amine (III) using a coupling reagent, typically HATU or HBTU. In certain instances two coupling products can be formed and are separated by preparative HPLC.

[0062] The desired primary aminopyrazole (III) can be prepared from nitropyrazole (V) through an alkylation (compound of type (VI)) and a reduction step. For the reduction step, zinc, iron or palladium are preferentially used.

[0063] Aminopyrazoles of type (III) can be prepared via a Curtius rearrangement as well (Scheme 3). A suitable ester from the pyrazole-3-carboxylic acid (VIII) can be alkylated to compound (IX). Saponification leads to carboxylic acid (X), and subsequent Curtius rearrangement leads to the aminopyrazole (III).

[0064] The corresponding benzyl chlorides, benzyl bromides, or benzyl mesylates necessary for the alkylation steps described in Schemes 2 (V → VI) and 3 (VIII → IX) can be prepared according to standard literature procedures or as described in the examples below.

[0065] The carboxylic acids of type (IV) can be prepared according to known procedures. In particular, a Negishi coupling (Scheme 4), or a similar carbon-carbon coupling between an (hetero)aryl bromide of type (XI) and (2-(tert-butoxy)-2-oxoethyl)zinc(II) bromide leads to the ester of type (XII): Hydrolysis, generally under acidic conditions, leads to the acid of type (IV). Bromide of type (XI) is either commercially available, or can be prepared according to known procedures (see experimental part).

[0066] Alternatively, a benzoic acid of type (XIII) can be transformed into an acid of type (IV) via a Wolff rearrangement (Scheme 5). The acid of type (XIII) can be reduced to an alcohol of type (XIV). This alcohol can then be activated to a compound of type (XV), wherein LG represents a leaving group such as chloride, bromide, mesylate or tosylate, and homologated to nitrile of type (XVI): Hydrolysis would then lead to an acid of type (IV).

[0067] Whenever the compounds of formula (I) are obtained in the form of mixtures of enantiomers, the enantiomers can be separated using methods known to one skilled in the art: e.g. by formation and separation of diastereomeric salts or by HPLC over a chiral stationary phase such as a Regis Whelk-O1(R,R) (10 µm) column, a Daicel ChiralCel OD-H (5-10 µm) column, or a Daicel ChiralPak IA (10 µm), IC (5 µm) or AD-H (5 µm) column. Typical conditions of chiral HPLC are an isocratic mixture of eluent A (EtOH, in presence or absence of an amine such as triethylamine or diethylamine) and eluent B (heptane), at a flow rate of 0.8 to 150 mL / min.EXPERIMENTAL PART

[0070] General procedure 1 for the preparation of acid chlorides. The desired carboxylic acid (1 eq.) is dissolved in toluene (5 mL / mmol). DMF (about 1 drop / mmol) and oxalyl chloride (1.5 eq.) are added, and the mixture is stirred at rt for 2 h. The solvents are removed under reduced pressure. The excess oxalyl chloride is removed azeotropically with toluene several times under reduced pressure. The residue is dried under high vacuum to yield the desired crude acid chloride.

[0071] General procedure 2 for an amide coupling. To a sol. of the desired amine (1 eq.) in dioxane (5 mL / mmol) is added the acid chloride (crude, 1.1 eq.) The mixture is heated to 60 °C to 90 °C for 1 h (or longer if the reaction is not complete). The mixture is allowed to cool to rt and the solvents are removed under reduced pressure. The residue is directly purified by automated FC, or by HPLC, to yield the desired product. Alternatively, the product can be isolated by crystallization.

[0072] General procedure 3 for an amide coupling. Unless indicated otherwise, a mixture of the desired carboxylic acid (1 eq.), the desired amine (1.5 eq), N-methylmorpholine (4 eq.) and HBTU (2 eq.) in DMF (around 20 mL / eq.) is stirred until the reaction is complete (a few hours to overnight). Other bases, coupling reagents and / or solvents can be used as well, see experimental details. The solvents are removed under reduced pressure. An aq. work-up (basic and / or acidic) is optionally realized. The residue is purified by automated FC, or by HPLC, to yield the desired product. Alternatively, the product can be isolated by crystallization.

[0073] General procedure 4 for the N-alkylation of 5-nitro-1H-pyrazole. K 2 CO 3 or NaH is added to a sol. of 5-nitro-1H-pyrazole in acetone or DMF or THF. The mixture is stirred for 15-30 min. The desired electrophile and Bu 4 NBr are added. The mixture is stirred efficiently at rt until the reaction is complete. The mixture is optionally filtered (if K 2 CO 3 is used) or quenched with water (if NaH is used), and the filtrate is evaporated under reduced pressure. The residue is partitioned between water and EtOAc. The org. layer is dried over MgSO 4 , filtered, and the solvents are removed under reduced pressure. Purification of the crude by automated FC or by HPLC yields the desired product.

[0074] General procedure 5 for the reduction of a nitro group. Fe or Zn is added to a sol. of the starting material in EtOH or acetone with aq. sat. NH 4 Cl. The mixture is heated to 75 °C and stirred at this temperature until the reaction is complete (about 1 h). The mixture is allowed to cool to rt and filtered through Celite®. The solvents were removed under reduced pressure to yield the desired crude product.

[0075] General procedure 6 for a Negishi coupling. A sol. of bromoaryl / bromoheteroaryl, (2-(tert-butoxy)-2-oxoethyl)zinc(II) chloride (0.5M in Et 2 O), palladium catalyst, and optionally a ligand in THF is stirred between rt and 90 °C until the starting materials are consumed. The mixture is allowed to cool to rt, and the solvents are removed under reduced pressure. Chromatographic purification yields the desired compound.

[0076] General procedure 7 for the hydrolysis of a tert-butyl ester. A sol. of the ester and an acid with optionally CH 2 Cl 2 is prepared at 0 °C. This mixture is stirred between at 0 °C, optionally warming up to rt, until consumption of the starting material. The solvents are removed under reduced pressure to yield the crude desired compound.

[0077] General procedure 9 for the N-alkylation of a pyridine. A mixture of 2,5-dibromopyridine, an amine, and DBU in DMSO is stirred at 80 °C until the reaction is complete. The amine and DBU may have to be added several times. The mixture is allowed to cool to rt, and the solvents are removed under reduced pressure. Purification of the crude by FC yields the desired product.Analytical conditions for LC-MS
