[0001] METHODS OF PREPARING NEK7 ACTIVITY MODULATORS
[0002] FIELD OF THE INVENTION
[0003] The invention disclosed herein provides improved medium-scale and large-scale processes for the preparation of chemical entities (e.g., a compound or a pharmaceutically acceptable salt thereof) that degrade and / or otherwise inhibit NIMA Related Kinase 7 (NEK7).
[0004] BACKGROUND
[0005] The processes of the present invention are useful for the preparation of compounds (or pharmaceutically acceptable salts thereof) that degrade and / or otherwise modulate (e.g., inhibit) NIMA Related Kinase 7 (NEK7). Said compounds are useful, e.g., for treating a subject (e.g., a human subject) having one or more disorders or diseases associated with NLRP3 inflammasome activation. Said disorders or diseases include but are not limited to, autoinflammatory and autoimmune disorders (e.g., gout, inflammatory bowel disease, rheumatoid arthritis, multiple sclerosis), neurodegenerative diseases (e.g., Alzheimer's disease, Parkinson’s disease), cardiovascular and metabolic disorders (e.g. pericarditis, atherosclerosis, type 2 diabetes, obesity and metabolic syndrome), fibrotic disorders (e.g. interstitial lung disease, chronic kidney disease), haematology (e.g. anaemia of inflammation) and eye disorders (e.g. macular degeneration). It is believed that the chemical entities described herein directly target (e.g., directly bind to) NEK7, thereby altering (e.g., attenuating) the inflammatory response modulated by the NLRP3 inflammasome.
[0006] PCT / US2024 / 039292 discloses compounds that degrade and / or otherwise modulate (e.g., inhibit) NEK7. The compounds disclosed therein are according to Formula (I):
[0007]
[0008] or pharmaceutically acceptable salts thereof, and include in particular N-(3,5-dichloro-4-(2,6-dioxopiperidin-3-yl)benzyl)-2-methyl-2-(5-methylpyrimidin-2-yl)propanamide. The process for synthesis of this compound is disclosed in Example 1 of PCT / US2024 / 039292. An overview of the synthesis of N-(3,5-dichloro-4-(2,6-dioxopiperidin-3-yl)benzyl)-2-methyl-2-(5-methylpyrimidin-2-yl)propenamide, which is representative of the syntheses of compounds of Formula (I), is reproduced below.
[0009]
[0010] In the process disclosed above, the key benzylic amine intermediate (4) is obtained in a 7-step reaction sequence starting from 5-bromo-1,3-dichloro-2-methylbenzene. Key carboxylic acid intermediate (5), made in three steps from ethyl 2-(5-bromopyrimidin-2-yl)acetate, can be coupled with the key benzylic amine intermediate (4) to form compound 14. Other compounds of Formula (I) disclosed in PCT / US2024 / 039292 are prepared in an similar manner to that set out above for compound 14.
[0011] The processes of preparation of compounds of Formula (I) disclosed in PCT / US2024 / 039292 have several disadvantages. Specifically, these processes include the use of the following reagents: tetrachlorocarbon (a toxic perchlorinated solvent); trimethylsilyl cyanide (a potent poison that behaves equivalently to hydrogen cyanide); Pd2(dba)3(a scarce palladium catalyst); ethyl 2-(5-bromopyrimidin-2-yl)acetate as the starting material for key carboxylic acid intermediate (5) (scarcely available); and MeB(OH)2 (a potentially genotoxic reagent). Further, key intermediate carboxylic acid (5) shown above (and other equivalent intermediates in accordance with Formula (I) of PCT / US2024 / 039292) are unstable and rapidly degrade in solution via decarboxylation, and their ester precursors are oils and cannot be purified at scale. Lastly, many intermediates require purification via column chromatography, which is not feasible at scale.
[0012] There is therefore a need for a simple and cost-effective method for the production of compounds of Formula (I) of PCT / US2024 / 039292, particularly for methods which do not require the use of scarce or toxic reagents, or generate unstable intermediates, and which proceeds at higher yields than the previous route.

[0715] . Similarly, a pyridinyl or pyrimidinyl moiety that is described to be optionally substituted with hydroxyl encompasses pyridone or pyrimidone tautomeric forms.
[0716] Further, compounds described herein may exist in one or more stereoisomeric forms. In some cases, such forms may be described through an assignment of absolute configuration, whereas other cases, stereochemistry is unknown and may be assigned arbitrarily to isolated stereoisomers. Isolation of stereoisomers may be conducted using chiral separation.
[0717] Compounds described herein (for example compounds of Formula (I) or any subformula, or compounds of T able 1, or their synthetic precursors) having one enantiomeric form may epimerise into the other enantiomeric form if the chiral center is in a position susceptible to epimerization (for instance on the 3-position of the piperidine-2, 6-dione ring). Thus, unless it is specifically stated or the context indicates otherwise, disclosure of one stereoisomer with a chiral centre encompasses the isolated stereoisomer and a mixture, such as a racemic mixture, of the (R) and (S) stereoisomers if the stereoisomers epimerise.

[0743] The term “water-free” as used herein refers to the absence of water. This term may be used interchangeably with the term anhydrous. Where a reagent is described as water-free, it may comprise less than 5% water by weight, for example less than 4% water by weight, or less than 3% water by weight, or less than 1% water by weight, or less than 0.5% water by weight, or less than 0.1 % water by weight, or 0% water by weight.
[0744] The term “protecting group” as used herein refers to is a chemical group or functional group temporarily added to a molecule to shield or protect a reactive part of the molecule during a reaction. The protecting group can be easily removed at a later stage, restoring the original functional group present in the molecule. The protecting groups allows for controlling selectivity. Just as an example, a hydroxyl group (-OH) might be protected by converting it into a silyl ether (such as TBS) to prevent it from reacting during a certain step. After the reaction, the silyl group can be removed, regenerating the free hydroxyl group. Protecting groups include hydroxyl protecting groups (i.e. groups that protect alcohols or phenols, such as ethers, esters and silyl protecting groups), amine protecting groups (i.e. groups that protect amine functionalities, such as carbamates, sulfonamides, amides), carbonyl protecting groups (i.e. groups that protect aldehydes or ketones, such as acetals, ketals and hydrazones), carboxylic acid protecting groups (i.e. groups that protect carboxylic acids, such as esters and amides), and phosphate or thiol protecting groups (i.e. groups that protect phosphate or thiol groups such as alkyl, aryl esters and thioethers). Nonlimiting examples include tert-butyldimethylsilyl (TBD), tri methylsilyl (TMS), benzyl (Bn), methoxymethyl (MOM), trityl (Tr), acetals, ketals, dioxanes, tert-butyloxycarbonyl (Boc), benzyloxycarbonyl (Cbz), and Fmoc (fluorenylmethyloxycarbonyl).The term “catalyst” as used herein refers to a molecule that increases the rate of a chemical reaction without being consumed or permanently altered in the process. Catalysts include metal catalysts and organocatalysts. Metal catalysts include palladium, rhodium and nickel catalysts. For example, palladium catalysts include (Pd(PPh3)4, Pd(PtBu3)2, Pd(pda)2, Pd(dppf)Cl2, Pd(OAc)2, Pd2(dba)3). Nickel catalysts include (Ni(PPh3)4, Ni(acac)2, Ni(COD)2, NiCl2, Raney Ni).

[0745] The term “reducing agent” as used herein refers to a molecule that donates electrons to another molecule during a chemical reaction, causing that molecule to be reduced (i.e., it gains electrons). In the process, the reducing agent itself becomes oxidized (i.e. it loses electrons). Reducing agents include hydride reducing agent (for example, NaBH4 or LiAlH4), metallic reducing agents (for example Zinc, Iron or Magnesium) and metal ion reducing agents (for example, Iron (II) or Copper (I)).
[0746] The term “reagent” as used herein refers to a molecule used in a chemical reaction to cause or facilitate the reaction. Reagents as referred to herein include starting materials (reactants), catalysts and solvents.
[0747] The term “alkylating agent” as used herein refers to a compound that adds an alkyl group (a group derived from an alkane, such as a methyl group or an ethyl group) to another molecule. Non-limiting examples of alkylating agents include Mel, Etl, MeBr, EtBr, 1,2-dibromoethane, methyl tosylate, ethyl tosylate, methyl sulfonyl chloride, ethyl sulfonyl chloride, methyl triflate, diazomethane dimethyl sulfate (DMS) and diethyl sulfate (DES).
[0748] The term “leaving group” as used herein refers to a group or atom that detaches from a molecule during a chemical reaction, typically in a substitution or elimination process, to form a stable entity after the bond breaks. Leaving groups include halides (for example, fluoride, chloride, bromide and iodide), sulfonate esters (for example, tosylate, mesylate and triflate), sulphate groups, alcohols, water and amines. Specific leaving groups used herein include Cl, Br, I, OH, OM, O(C=O)(C1-6 alkyl), O(C=O)(N3), O(C1-6 alkyl), and S(C1-6 alkyl).
[0749] The term “ligand” as used herein refers to a molecule or ion that binds to a central metal atom or ion in a coordination complex, forming a coordination bond. Ligands can be simple ions (e.g. chloride) or more complex molecules (e.g. ethylenediamine) that donate one or more pairs of electrons to the metal centre to form the bond. Ligands described herein may be monodentate, bidentate or polydentate ligands.
[0750] Macrocyclic ligands are also included. Exemplary ligands include phosphine ligands, for example 1,1 ’-Bis(diphenylphosphino)ferrocene (dppf), 2-Dicyclohexylphosphino-2’,6’-dimethoxybiphenyl (SPhos), 1,3-Bis(diphenylphosphino)propane (dppp), 1,4-Bis(diphenylphosphino)butane (dppb), and Xantphos (4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene), Bis(diphenylphosphino)methane (DPPM), 1,2-Bis(diphenylphosphino)ethane (DPPE), 1,2-Bis(dicyclohexylphosphino)ethane (DCPE), PPhs, P(c-hex)3, P(‘BU)3, P(C6F5)3, and P(2,4,6-Me3C6H2)3.
[0751] The term “additive” as used herein refers to a substance that is added in small quantities to another substance to enhance or modify its properties, performance, or behaviour. For example, the additive may act as a stabiliser to prevent degradation of another molecule during a reaction. Exemplary additives include antioxidants, such as BHT, or additives for use with coupling reagents, for example those used in order to enhance reactivity and reduce the formation of epimers and N-acyl ureas during amide coupling reactions (for example, HOBt (1 -Hydroxybenzotriazole), HOOBt (HODhbt) (Hydroxy-3, 4-dihydro-4-oxo-1,2,3-benzo-triazine), HOSu (N-Hydroxysuccinimide), HOAt (1-Hydroxy-7-aza-1 H-benzotriazole), Ethyl 2-cyano-2-(hydroximino)acetate and DMAP (4-(N, N-Dimethylamino)pyridine)).The term “flow conditions” as used herein refers to reaction conditions in which reactions are conducted within a system (e.g. a flow reactor) that maintains a continuous and controlled flow of reagents through the system. Use of “flow conditions” allows for control over reaction conditions, for example the temperature, pressure, mixing rate and / or reaction time. It may include pumping fluid into a flow reactor or contacting two or more fluids via tubes of a flow reactor that join one another at a controlled rate. The flow reactor may be a Plug Flow Reactor (PFR), a Continuous Stirred-Tank Reactor (CSTR), a Tubular Flow Reactor, a Microflow Reactor, a Packed-Bed Flow Reactor, a Trickle-Bed Reactor, a Monolithic Flow Reactor, a Loop Flow Reactor, an Oscillatory Flow Reactor or a Spinning Disc Flow Reactor. “Flow conditions” do not include conditions for static or batch-based chemical reactions, for example static or batch-based chemical reactions carried out prior to or subsequent to the reaction carried out under flow conditions. The reaction carried out under flow conditions may nevertheless be used in conjunction with static or batch-based chemical reactions carried out prior to or subsequent to the reaction carried out under flow conditions (for example, static or batch-based reaction workups or purifications).
[0752] The term “residence time” as used herein refers to the average time that a molecule spends under certain reaction conditions (e.g., inside a reactor before leaving it). For example, when used in the context of flow conditions, the term “residence time” as used herein refers to the average time that a molecule spends under flow conditions (e.g., within a flow reactor before leaving it). Controlling the residence time may allow for certain factors of a synthesis (e.g., conversion of reagents, selectivity and yield) to be optimised.
[0753] The reactions described herein can be run for as long as needed to achieve completion of the reaction, or at least an acceptable yield of product. For example, the duration of the reaction may be less than 1 minute, less than 5 minutes, less than 10 minutes, less than 30 minutes, less than 1 hour, less than 2 hours, less than 3 hours, less than 5 hours, less than 10 hours, less than 20 hours, less than 30 hours less than 40 hours, less than 50 hours, less than 60 hours, less than 70 hours, less than 80 hours, less than 90 hours, or less than 100 hours. The reaction time may depend, inter alia, on the scale of the reaction. The skilled person can monitor the progress of the reaction in a number of different ways including by monitoring physical changes such as a change in colour, or by monitoring the reaction using analytical methods such as NMR, FT-IR, XRPD, or chromatography, for example thin layer chromatography (TLC) or liquid chromatography coupled to mass spectrometry (LC-MS).
[0754] Upon completion of the reactions described herein, the reaction mixture is optionally purified. Purification techniques are known to the skilled person and include: chromatography (e.g. HPLC, which may be reverse phase or normal phase); liquid-liquid separation, for example using multiple immiscible solvents; and / or liquid-solid separation, for example using filtration, decantation, (re)crystallisation (e.g. concentration induced crystallisation, antisolvent crystallisation and cooling induced crystallisation), trituration, evaporation, freeze drying.
[0755] The reactions described herein may be performed on any suitable scale. In one embodiment, the reaction mixture is of industrial scale. It may for example have a volume of at least 1 I, in particular at least 10 I, at least 100 I, or at least 1000 I. In another embodiment, the reaction mixture is of microscale. It may for example have a volume of 10 ml or less, in particular 1 ml or less, 100 pl or less, 10 pl or less or 1 pl or less.
[0756] The reactions described herein may be part of a series of reactions comprising a synthesis. Where multiple reactions are described, these can be conducted in a sequential fashion or in a one-pot fashion. Sequential reactions typically involve the completion of a first reaction, followed by work up and purification of that reaction, before a second reaction is conducted, continuing with further reactions until the desired product has been made. In contrast, in a one-pot fashion, a first reaction may be completed, and then asecond reaction may be conducted using one or more products of the first reaction without isolation. One pot reactions are advantageous because they avoid unnecessary purification steps, saving time and materials.
[0757] The expression "comprise", as used herein, besides its literal meaning also includes and specifically refers to the expressions "consist essentially of and "consist of. Thus, the expression "comprise" refers to embodiments wherein the subject-matter which "comprises" specifically listed elements may and / or indeed does encompass further elements as well as embodiments wherein the subject-matter which "comprises" specifically listed elements does not comprise further elements.
[0758] Numeric ranges described herein are inclusive of the numbers defining the range. The headings provided herein are not limitations of the various aspects or embodiments of this invention which can be read by reference to the specification as a whole. According to one embodiment, subject matter described herein as comprising certain steps in the case of methods or as comprising certain ingredients in the case of compositions refers to subject matter consisting of the respective steps or ingredients.

The filter cake was dissolved in THF (5 L), dried over MgSO4, filtered, and the filter cake was washed with THF (1 L) to obtain Filtrate 1. The mother liquor was diluted with THF (10.5 L), dried over MgSO4, filtered, and the filter cake was washed with THF (2 L) to obtain Filtrate 2.

LiHMDS 1 M in THF solution (2.20 eq.) was added over 1 h. The reaction was stirred at 40 °C until completion was confirmed by sampling and HPLC analysis (1 h). The mixture was cooled to 20 °C, and acetic acid (4.5 eq.) was added to quench the reaction (pH 4 ~ 5). The mixture was concentrated to 1-2 V at 50 °C, then more acetic acid (1.5 eq.) was added, followed by MeOH (10 V), and the mixture was concentrated to 4-5 V at 50 °C. Water (10 V) was added, and the mixture was cooled to 0 °C and stirred for 16 h. It was filtered, and the filter cake was washed with MeOH / H2O 1 / 1 (2 V). After drying at 45 °C for 24 h, the cake still contained water and salts, so it was reworked. The filter cake was redissolved in THF (7 V), filtered over Celite, and the Celite was washed with THF (1 V). Water was separated, and the mixture was concentrated to 2 V. More THF (5 V) was added to dissolve the solids and separate more water. The organic phase was dried with Na2SO4, filtered, the cake was washed with THF (1 V), and the filtrate was concentrated to 2 V at 50 °C. Solids precipitated, so MeOH (10 L) was added, and the mixture was concentrated to 5 L at 50 °C. Solids once again precipitated, so water (10 V) was slowly added to the mixture, and it was cooled to 6 °C. It was filtered, and the filter cake was washed with EtOH / H2O 1 / 1 (2 V) at 0 °C. The wet cake (4.8 kg) was dried in an oven at 45 °C. To improve the assay purity, the solid was reworked a second time. The solid (1.29 kg, 2.871 mol. 1.00 eq.) was dissolved in DCM (9 V) and MeOH (1 V). The organic phase was washed with water twice (1 x 5 V, then 1 x 2 V), then it was concentrated to 4-5 V at 40 °C. Ethyl acetate (5 V) was added, and the mixture was stirred at 25 °C for 1 h. Solids gradually precipitated. The mixture was concentrated once again to 4-5 V at 40 °C. Ethyl acetate (5 V) was added, and the mixture was concentrated to 4-5 V at 40 °C. n-heptane (5 V) was added, and the mixture was concentrated to 4-5 V at 40 °C (this was done twice).
