Abstract
Description
[Technical Field]
[0001] Related Applications This application claims the benefit of priority to U.S. Patent Application No. 63 / 398,939, filed August 18, 2022, which is incorporated herein by reference in its entirety. [Background technology]
[0002] Myeloperoxidase (MPO) is a heme-containing enzyme primarily expressed in neutrophil granulocytes (neutrophils). MPO is one member of a diverse family of mammalian peroxidase proteins, which also includes eosinophil peroxidase (EPX), lactoperoxidase (LPO), and thyroid peroxidase (TPO). MPO is activated by hydrogen peroxide, the source of which can be NADPH-derived superoxide anion catalyzed by superoxide dismutase (SOD), xanthine oxidase-derived superoxide anion, and hydrogen peroxide formed during purine oxidation. MPO catalyzes the two-electron oxidation of halides (primarily chloride) and pseudohalides (e.g., thiocyanate) to form the germicidal hypohalous acids hypochlorous acid (bleach) and hypothiocyanous acid. These in turn can act on multiple protein, lipid and nucleic acid targets, causing dysfunction and further inflammation. 1 Furthermore, MPO catalyzes the one-electron oxidation of numerous electron-rich substrates through the so-called peroxidation cycle, generating free radicals that are themselves harmful (e.g., urate radicals). 2 ), or by directly oxidizing nitric oxide (NO) or by generating free radicals that oxidize NO, resulting in free radicals that can interfere with NO-driven physiological functions. 1 .
[0003] Numerically, neutrophils are the predominant leukocyte population (50-70% of blood leukocytes in humans) and are a highly dynamic cell population that is part of the first line of defense against stressors, whether microbial or sterile. Within neutrophils, preformed MPO is stored in millimolar concentrations in granules, which fuse with phagosomes containing engulfed microorganisms, leading to MPO activation and microbial killing. 3 Furthermore, MPO can also be released outside the cell, where its oxidative activity can cause damage to adjacent tissues and dysfunction or regulation of biochemical and cellular processes, such as tissue remodeling and fibrosis. This release can occur as a result of either degranulation or NETosis, which releases webs of decondensed DNA coated with intracellular proteins such as MPO, so-called neutrophil extracellular traps (NETs). 4 Furthermore, MPO is also released constitutively. 5 The enzyme is highly cationic and therefore becomes trapped extracellularly in negatively charged structures such as proteoglycans on the extracellular matrix in the vascular wall and interstitium. 6 .
[0004] Given the dominance of neutrophils in inflammatory biology and the abundance of MPO in neutrophils (estimated at 5% of the cell's dry weight), it is not surprising that numerous disease states have been hypothesized to involve the pathological role of myeloperoxidase. Such conditions include not only "traditional" inflammatory diseases such as inflammatory bowel disease and autoimmune diseases, rheumatoid arthritis, and systemic lupus erythematosus, but also other common diseases in which inflammation appears as an important pathophysiological component, such as cardiovascular disease, neurodegenerative diseases, renal disease, respiratory disease, metabolic disease, obesity, and cancer. 1 .
[0005] The pathophysiological role of MPO is further supported by human genetic studies and rodent intervention studies. 7 and tissue MPO activity 8A common polymorphism in the MPO promoter regulating coronary microvascular dysfunction 9 , mortality in heart failure 10 , risk of coronary artery disease 11 and its outcomes 12 , risk of developing hepatitis C-related liver fibrosis and cirrhosis 13、14 and the risk of hepatocellular carcinoma and death in alcohol-related cirrhosis 15 In vivo studies in rodents and in vitro studies in humans have reported the efficacy of selective MPO inhibitors for several diseases and / or conditions, including preservation of cardiac function in post-myocardial infarction models. 16 , stabilization of atherosclerotic plaque 17 , pulmonary arterial hypertension 18 , glomerulonephritis 19 and cystic fibrosis 20 Improvement of fatty liver and liver fibrosis 21 22 reduction of vascular dysfunction in conditions of inflammatory vascular dysfunction 23 , normalization of microvascular function 24 , improved relaxation in human cardiomyocytes 25 , and inhibition of neutrophil nephrosis in human neutrophils 26 .
[0006] Although the contribution of MPO to these various disease states may vary depending on the condition, several mechanisms appear to be important in some of these conditions: damage and dysfunction caused by MPO-derived reactive oxygen species, such as hypochlorous acid; 1 In addition, MPO also induces neutrophil activation 27 , and through activation of proteinases that cleave the latent form into active effector proteins, e.g., cytokines. 28 MPO appears to play a regulatory role in inflammation, acting to amplify the inflammatory response. The mechanistic link between MPO and fibrosis is also likely multifactorial, e.g., i) secondary to increased inflammation, ii) through activation of myofibroblasts. 29 and iii) increased collagen secretion itself. 30Finally, active MPO directly (and indirectly) oxidizes NO via the peroxidative cycle, thereby impairing nitric oxide-driven mechanisms such as smooth muscle cell relaxation. 31 This latter mechanism involves MPO being sequestered on proteoglycans, transcytosed by endothelial cells, and spatially deposited in the subendothelial compartment between NO-producing endothelium and NO-receptor smooth muscle. 32 Therefore, the relationship between MPO and microvascular dysfunction and the resulting impaired blood supply to tissues may be of particular importance.
[0007] In summary, there is a medical need and sound rationale for orally active MPO inhibitors for the treatment of chronic inflammatory conditions. To increase the therapeutic index of such agents, it is necessary to obtain MPO inhibitors that are selective for MPO over TPO. The thyroid gland is a key regulator of thermogenesis and metabolic function, and TPO plays a central role through iodination of tyrosine residues to form the thyroid hormones T4 and T3. TPO activation is under the control of thyroid-stimulating hormone, and T4 and T3 are part of a negative feedback mechanism; thus, decreased levels of T3 and T4 upon TPO inhibition result in a compensatory increase in thyroid-stimulating hormone. 33 .
[0008] WO 2003 / 089430, WO 2005 / 037835, WO 2007 / 120097, WO 2007 / 120098 and WO 2007 / 142576 disclose thioxanthine derivatives and their use as MPO inhibitors in therapy.
[0009] WO 2006 / 062465 and WO 2007 / 142577 disclose 2-thioxo-1,2,3,4-tetrahydro-pyrrolo[3,2-d]pyrimidin-4-one derivatives that are claimed to be inhibitors of MPO. These compounds are said to be selective for related enzymes such as TPO.
[0010] WO 2009 / 025618 discloses the use of thioxanthine and 2-thioxo-1,2,3,4-tetrahydro-pyrrolo[3,2-d]pyrimidin-4-one derivatives and MPO inhibitors for the treatment of multiple system atrophy (MSA) and Huntington's disease (HD), and for neuroprotection.
[0011] J. Labeled Compounds and Radiopharmaceuticals, 2012, 55, 393-399, discloses several tritium-labeled thioxanthine derivatives, 13C-labeled thioxanthine derivatives, and 14C-labeled pyrrolo[3,2-d]pyrimidin-4-one compounds, which are described as inactivators of MPO.
[0012] J. Biol. Chem., 2011, 286, 37578-37589 discloses certain thioxanthine derivatives. These compounds are described as inhibiting plasma MPO and reducing protein chlorination in mouse models. These compounds are also claimed to be weak inhibitors of TPO.
[0013] WO 2013 / 068875 discloses thiopyrimidone derivatives that are alleged to be MPO inhibitors.
[0014] WO 2016 / 087338 discloses thioxopyrrolopyrimidone derivatives that are said to be MPO inhibitors.
[0015] Therefore, there is a need for novel therapeutically useful MPO inhibitors, as well as novel MPO inhibitors with improved selectivity for the MPO enzyme over the TPO enzyme and suitable pharmacological properties. DETAILED DESCRIPTION OF THE INVENTION

[0252] For the avoidance of doubt, the term "treatment" as used herein includes therapeutic treatment and / or prophylactic treatment.
[0253] When a compound or salt described herein is administered as therapy to treat a disorder, a "therapeutically effective amount" is an amount sufficient to reduce or completely alleviate the symptoms or other deleterious effects of the disorder, cure the disorder, reverse, halt entirely, or slow the progression of the disorder, or reduce the risk of the disorder worsening.

[0255] The compounds described herein have the advantage that they may be more effective, less toxic, more selective, more potent, produce fewer side effects, be more easily absorbed, and / or have a better pharmacokinetic profile (e.g., higher oral bioavailability and / or lower clearance) than compounds known in the prior art.
[0256] Combination therapy A compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), or a compound disclosed herein, or a pharmaceutically acceptable salt thereof, may be administered in conjunction with other compounds used in the treatment of the above conditions.
[0257] In some embodiments, a compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), or a compound disclosed herein, or a pharmaceutically acceptable salt thereof, is administered simultaneously, sequentially, or in admixture with a second active ingredient for the treatment of one or more of the conditions listed above. Such combinations may be used in conjunction with one or more additional active ingredients.
[0258] The compounds described herein are useful in treating cardiovascular, metabolic and renal diseases as the following agents: Heart medications, antihypertensive drugs, Diuretics, peripheral vasodilators, Lipid-modifying drugs, antidiabetic drugs, anti-inflammatory drugs, or Anticoagulants can be used in combination with

[0260] When used in combination therapy, it is contemplated that the compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa), or (IVb), or a compound disclosed herein, or a pharmaceutically acceptable salt thereof, and other active ingredients may be administered in a single composition, completely separate compositions, or a combination thereof. It is also contemplated that the active ingredients may be administered concurrently, simultaneously, sequentially, or separately. The specific composition(s) and frequency(ies) of the combination therapy will depend on various factors, including, for example, the route of administration, the condition being treated, the patient's species, any interactions that may occur between the active ingredients when combined in a single composition, any interactions between the active ingredients when administered to an animal patient, and various other factors known to physicians (in the case of human patients), veterinarians (in the case of non-human patients), and others skilled in the art.
[0261] Pharmaceutical Composition Methods for treating a condition in which inhibition of MPO is required are provided, comprising administering to a human suffering from or susceptible to such a condition a therapeutically effective amount of a compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), or a compound disclosed herein, or a pharmaceutically acceptable salt thereof.
[0262] The compounds of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), or compounds disclosed herein, or pharmaceutically acceptable salts thereof, are typically administered orally, topically, parenterally, intravenously, intramuscularly, subcutaneously or via other injection methods, buccal, rectal, vaginal, transdermal and / or nasal routes, and / or via inhalation in the form of a pharmaceutical preparation containing the active ingredient or a pharmaceutically acceptable salt thereof in a pharmaceutically acceptable dosage form. Depending on the disorder and patient being treated and the route of administration, the composition may be administered in various dosages. Conventional procedures for the selection and preparation of appropriate pharmaceutical formulations are described, for example, in "Pharmaceuticals - The Science of Dosage Form Designs," MEAulton, Churchill Livingstone, 2002. nd It is described in Ed.2002.
[0263] The optimal dosage and frequency of administration will depend on the particular condition being treated and its severity, the patient species, the age, sex, size and weight, diet, and general health of the particular patient, brain / body weight ratio, other medications the patient may be taking, the route of administration, the formulation, and a variety of other factors known to physicians and others skilled in the art.
[0264] In some embodiments, a pharmaceutical formulation is provided comprising a compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), a compound disclosed herein, a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable derivative thereof, in admixture with a pharmaceutically acceptable adjuvant, diluent or carrier.
[0265] A compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), or a compound disclosed herein, or a pharmaceutically acceptable salt thereof, may be present in the pharmaceutical formulation at a concentration of 0.1 to 99.5% by weight, such as 0.5 to 95% by weight, of the total formulation.
[0266] Some embodiments include a pharmaceutically acceptable salt of a compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb).
[0267] Some embodiments include pharmaceutically acceptable salts of the compounds disclosed herein.
[0268] Such salts may be advantageous due to one or more of their chemical or physical properties, such as stability at different temperatures and humidities, or desirable solubility in HO, oil, or other solvents. In some cases, salts may be used to aid in the isolation or purification of the compound. In some embodiments (particularly when the salt is intended for administration to an animal, e.g., a human, or when the salt is a reagent for use in making a compound or salt intended for administration to an animal), the salt is pharmaceutically acceptable.
[0269] The term "pharmaceutically acceptable" is used to characterize a moiety (e.g., a salt, dosage form, or excipient) as appropriate for use according to sound medical judgment. Generally, a pharmaceutically acceptable moiety has one or more benefits that outweigh any adverse effects that the moiety may have. Adverse effects may include, for example, excessive toxicity, irritation, allergic response, and other problems and complications.
[0270] When the compound is sufficiently basic, pharmaceutically acceptable salts include, but are not limited to, inorganic or organic acid addition salts.
[0271] For a review on suitable salts see Berge et al., J. Pharm. Sci., 1977, 66, 1-19 or Handbook of Pharmaceutical Salts: Properties, selection and use, PH Stahl, PG Vermuth, IUPAC, Wiley-VCH, 2002.
[0272] If the acid co-component is a solid at room temperature and there is no or only partial proton transfer between a compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa), or (IVb), or a compound disclosed herein, and such an acid co-component, a co-crystal of the co-component with the compound, rather than a salt, may form. All such co-crystal forms of a compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa), or (IVb), or a compound disclosed herein, are encompassed herein.
[0273] It is also understood that certain compounds of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), or certain compounds disclosed herein, may exist in solvated forms, such as hydrates, including solvates of a compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), or a pharmaceutically acceptable salt of a compound disclosed herein.
[0274] In some embodiments, certain compounds of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa), or (IVb), or certain compounds disclosed herein, may exist as racemates and racemic mixtures, single enantiomers, individual diastereomers, and diastereomeric mixtures. Certain compounds of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa), or (IVb), or certain compounds disclosed herein, may contain bonds (e.g., carbon-carbon bonds, carbon-nitrogen bonds such as amide bonds) where bond rotation is restricted about that particular bond, for example, due to the presence of a ring bond or double bond. Stereoisomers may be separated using conventional techniques, for example, chromatography or fractional crystallization, or they may be made by stereoselective synthesis.
[0275] In some embodiments, compounds of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), compounds disclosed herein, and pharmaceutically acceptable salts thereof, encompass any isotopically labeled (or "radiolabeled") derivatives of such compounds. Such derivatives are derivatives of the above compounds in which one or more atoms have been replaced by atoms having an atomic mass or mass number different from the atomic mass or mass number typically found in nature. Examples of isotopes that may be incorporated include: 2 H (also written as "D" for deuterium) may be mentioned.
[0276] In some embodiments, the compounds of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), and compounds disclosed herein, may be administered in the form of a prodrug or a pharmaceutically acceptable salt thereof, which is broken down in the human or animal body to yield said compound of Formula (I), (Ia), (Ib), (II), (IIa), (IIb), (III), (IIIa), (IIIb), (IV), (IVa) or (IVb), or a compound disclosed herein.
[0277] Various forms of prodrugs are known in the art, see Nature Reviews Drug Discovery 2008, 7, 255 and references cited therein for examples of prodrug derivatives.

[0279] The following abbreviations were used:
[0280] [Table 1-1]
[0281] [Table 1-2]
[0282] General conditions (i) The operations were carried out under an atmosphere of an inert gas such as N2 at room temperature (rt), i.e., in the range of 17 to 28°C; (ii) where the reaction is referred to as being degassed or purged, this can be accomplished, for example, by purging the reaction solvent with a constant flow of nitrogen for a suitable period of time (e.g., 5-10 minutes), or by repeatedly evacuating the vessel and backfilling it with a suitable inert atmosphere (e.g., nitrogen(g) or argon(g)); (iii) if the reaction refers to the use of a microwave reactor, use one of the following microwave reactors: Biotage Initiator, Personal Chemistry Emrys Optimizer, Personal Chemistry Smith Creator, or CEM Explorer; (iv) the progress of the reaction is generally followed by thin layer chromatography (TLC) and / or analytical high performance liquid chromatography (HPLC or UPLC), usually coupled to a mass spectrometer (LCMS); (v) When necessary, organic solutions were dried over anhydrous MgSO or NaSO, or dried using an ISOLUTE® Phase Separator, and work-up procedures were carried out using conventional phase separation techniques. For example, when using a drying agent such as MgSO or NaSO to dry the organic layer, it is understood that the organic layer will be filtered before being concentrated. (vi) evaporation was performed either by rotary evaporation in vacuo or in a Genevac HT-4 / EZ-2 or Biotage V10; (vii) Unless otherwise stated, flash column chromatography was performed on normal-phase silica using either Merck Silica Gel (Art. 9385) or preparatively packed cartridges such as Biotage® SNAP cartridges (40-63 μm silica, 4-330 g), Biotage® Sfar silica HC D cartridges (20 μm, 10-100 g), Interchim puriFlash™ cartridges (25 μm, 4-120 g), Interchim puriFlash™ cartridges (50 μm, 25-330 g), Grace® GraceResolv™ Silica Flash cartridges (4-120 g) or Agela Flash Column Silica-CS cartridges (80-330 g), or on reverse-phase silica, spherical cartridges (20-35 μm, 100 A, 80-330 g) using Agela Technologies C-18. performed manually or automated using the Reveleris® X2 Flash System or similar system; (viii) Preparative reversed-phase HPLC and preparative reversed-phase SFC were performed using standard HPLC and SFC instruments, respectively, equipped with either MS and / or UV-triggered fraction collection instruments, using either an isocratic or gradient mobile phase, as described in the Experimental Section; The relevant fractions were collected, combined, and lyophilized or evaporated to give the purified compound, or the relevant fractions were collected, combined, concentrated under reduced pressure, extracted with DCM or EtOAc, and the organic phase was dried over Na2SO4 or by using a phase separator and then concentrated under reduced pressure to give the purified compound. (ix) Chiral preparative chromatography was performed using HPLC or SFC on standard HPLC or SFC equipment, respectively, using either isocratic or gradient runs with mobile phases as described in the Experimental Section; (x) yields, if any, are not necessarily the maximum achievable and, if necessary, reactions were repeated when larger amounts of reaction product were required; (xi) When a particular compound is obtained as an acid addition salt (e.g., a monohydrochloride or dihydrochloride), the stoichiometry of the salt is based on the number and nature of the basic groups in the compound, and the exact stoichiometry of the salt is not generally determined, for example, by elemental analysis data; (xii) In general, the structures of the final products of the compounds described herein were confirmed by nuclear magnetic resonance (NMR) and / or mass spectrometry techniques; proton NMR chemical shift values were 300, 400, 500 and 600 MHz, respectively. 1 Measurements were made on a Bruker Avance III 300, 400, 500, and 600 spectrometer operating at H frequencies on the delta scale. Experiments were typically recorded at 25°C. Chemical shifts are given in ppm with the solvent as the internal standard. Protons on heteroatoms, such as NH and OH protons, are reported only if detected in the NMR and may therefore be missing. In certain instances, protons may be masked or partially masked by the solvent peak and therefore either missing and not reported, or reported as a multiplet overlapping with the solvent. The following abbreviations (and their derivatives, e.g., dd, doublet of doublets, etc.) are used: s, singlet; d, doublet; t, triplet; q, quartet; m, multiplet; br, broad; qn, quintet; p, pentet. In some cases, the final product structures of the compounds disclosed herein may appear as rotamers in the NMR spectrum, in which case only the peak of the major rotamer is reported. Electrospray mass spectral data were obtained using a Waters Acquity UPLC coupled to a Waters single quadrupole mass spectrometer or similar instrument, acquiring both positive and negative ion data, generally only ions associated with the parent structure being reported; high-resolution electrospray mass spectral data were obtained using a Waters XEVO qToF mass spectrometer or similar instrument, acquiring either positive or negative ion data, generally only ions associated with the parent structure being reported; (xiii) intermediates were not necessarily completely purified, but their structure and purity were assessed by TLC, analytical HPLC / UPLC, and / or NMR analysis and / or mass spectrometry; (xiv) Unless otherwise specified, compounds containing asymmetric carbon and / or sulfur atoms were not resolved; (xv) Examples and intermediate compounds are generally named using PerkinElmer's ChemDraw Professional version 20.1.1.125, which generates names of chemical structures using the Cahn-Ingold-Prelog (CIP) rules for stereochemistry and follows IUPAC rules whenever possible when generating chemical names. Stereoisomers are cited by name and distinguished from one another by stereodescriptors assigned according to the CIP rules.
[0283] ChemDraw optionally uses stereocenter labels such as "&" and "or" in its drawings to describe the configuration of stereochemical centers present in a structure.
[0284] In general, chemical structures of examples and intermediates containing the label "&" at a stereocenter mean that the configuration of such example or intermediate at that stereocenter is a mixture of both (R) and (S); the label "or" means that the configuration of such example or intermediate is either (S) or (R) at the stereocenter. All unidentified absolute stereocenters "&" and "or" may be present in a single structure.
[0285] In general, the "&" and "or" labels at each stereocenter present in a structure may also include a number. The number may indicate whether the stereocenter varies independently of one another or not. Thus, if two or more stereocenters do not vary independently of one another, i.e., are fixed relative to one another, they have the same number, but if they vary independently of one another, they have different numbers. For example, if a compound has two stereocenters in a ring that are independent of one another, one stereocenter is labeled "or1" (or "&1") and the other is labeled "or2" (or "&2"); if a compound has two stereocenters in a ring that are fixed relative to one another and do not vary independently of one another, both stereocenters are labeled "or1" (or "&1"); if a compound has two stereocenters that are fixed relative to one another and a third stereocenter that varies independently of the former stereocenters, the first two stereocenters are both labeled "or1" (or "&1") and the third stereocenter is labeled "or2" (or "&2").
[0286] It is further noted that, as an artifact of this automatic labeling by ChemDraw, in some instances the two isomers are displayed side by side, with the stereocenter(s) of Isomer 1 labeled "or1" and the stereocenter(s) of Isomer 2 labeled "or2." It is understood that these two compounds are considered to be isomers of each other, as indicated by different properties, e.g., different elution times on chiral HPLC.
[0287] Generally, for chemical structures of examples and intermediates where all stereocenters present are racemic, no label is designated at the stereocenter(s) and the structures are drawn with a straight bond at each stereocenter.
[0288] In general, for example and intermediate structures where all stereocenters are designated as "&", the structures are named with the prefix "rac-". For example and intermediate structures where all stereocenters are designated as "or", the structures are named with the prefix "rel-".
[0289] Generally, the label "Isomer 1" corresponds to the first eluting isomer and "Isomer 2" corresponds to the second eluting isomer on a given chiral HPLC column and eluent, and is used to distinguish between two isomers containing one or more stereocenters with unknown absolute configuration.
[0290] Generally, for examples or intermediates containing two or more stereocenters, the relative stereochemistry is described using the configurational descriptors "S" and "R" for the stereocenters and the prefix "rac-" or "rel-" cited before the name.
[0291] Examples or intermediates named with the prefix "rel-" are single isomers, and the stereocenter(s) in the isomer are designated "R" or "S," although it is understood that the actual stereochemistry of that particular isomer may be the opposite of the label. For example, Example 12a (Isomer 1) is named "rel-(R)-1-(2-(4,4-difluoropiperidin-2-yl)benzyl)-2-thioxo-1,2,3,5-tetrahydro-4H-pyrrolo[3,2-d]pyrimidin-4-one," but Example 12a may be "(S)-1-(2-(4,4-difluoropiperidin-2-yl)benzyl)-2-thioxo-1,2,3,5-tetrahydro-4H-pyrrolo[3,2-d]pyrimidin-4-one." For example, Example 18b (Isomer 1) is named "rel-2-thioxo-3-(2-((2R,4R)-4-(trifluoromethyl)piperidin-2-yl)benzyl)-1,2,3,7-tetrahydro-6H-purin-6-one," but Example 18b can be "rel-2-thioxo-3-(2-((2S,4S)-4-(trifluoromethyl)piperidin-2-yl)benzyl)-1,2,3,7-tetrahydro-6H-purin-6-one."
[0292] Examples or intermediates named with the prefix "rac-" are mixtures of isomers, and the relative stereochemistry of the stereocenters in the isomers is designated by the descriptor "R" or "S," but it is understood that the actual stereochemistry of that particular isomeric mixture also includes the reverse of the descriptor. For example, Example 17b is named "rac-2-thioxo-1-(2-((2R,4R)-4-(trifluoromethyl)piperidin-2-yl)benzyl)-1,2,3,5-tetrahydro-4H-pyrrolo[3,2-d]pyrimidin-4-one," but Example 17b also includes "2-thioxo-1-(2-((2S,4S)-4-(trifluoromethyl)piperidin-2-yl)benzyl)-1,2,3,5-tetrahydro-4H-pyrrolo[3,2-d]pyrimidin-4-one."

[0299] [ka]
[0300] The conditions are such that reductive alkylation of a compound of formula (VIII) results in the formation of an N-C bond between the nitrogen atom of the compound of formula (VIII) and the carbon atom of the aldehyde group of a compound of formula (VII). The reaction conditions are conventional reductive alkylation conditions. Typically, the amine compound as a hydrochloride salt is treated with DIPEA or TEA and HOAc in an organic solvent such as EtOH, MeOH, DCM, or DCE in the presence of an aldehyde compound of formula (VII). After stirring the mixture for a period of time, e.g., at room temperature, a reducing agent such as NaBHCN, NaBH, or NaBH(OAc) is added, and the resulting mixture is stirred, typically at a temperature ranging from 20°C to 80°C, until the reaction is complete, e.g., for 1 to 20 hours, to give a compound of formula (VI). (See, e.g., J. Org. Chem 1996, 61, 3849.)
