[0002] Autoimmune diseases are associated with the overproduction of pro-inflammatory cytokines. One such pro-inflammatory cytokine is interleukin-1 (IL-1), produced by activated macrophages, monocytes, fibroblasts, and other components of the innate immune system, such as dendritic cells. IL-1 is involved in various cellular activities, including cell proliferation, differentiation, and apoptosis (Masters, SL et al., Annu. Rev. Immunol. 2009. 27:621–68).
[0003] In humans, 22 NLR proteins are divided into four NLR subfamilies based on their NW-terminal domains. NLRA contains a CARD-AT domain, NLRB (NAIP) contains a BIR domain, NLRC (including NOD1 and NOD2) contains a CARD domain, and NLRP contains a pyrin domain. Several NLR family members are involved in inflammasome formation.
[0004] Although inflammasome activation appears to have evolved into a crucial component of host immunity against pathogens, the NLRP3 inflammasome is unique in its ability to activate in response to endogenous aseptic danger signals. Many such aseptic signals have been elucidated, and their formation is associated with specific disease states. For example, uric acid crystals found in patients with gout are potent triggers for NLRP3 activation. Similarly, cholesterol crystals found in patients with atherosclerosis can also promote NLRP3 activation. The understanding of the role of aseptic danger signals as NLRP3 activators has led to the involvement of IL-1 and IL-18 in a wide range of pathophysiological indications, including metabolic disorders, physiological disorders, inflammatory disorders, hematologic disorders, and immune disorders.
[0005] This disclosure stems from the need to provide a novel method for preparing compounds for the specific regulation of NLRP3-dependent cellular processes. Summary of the Invention

[0029] Autoimmune diseases are associated with the overproduction of pro-inflammatory factors. One of these pro-inflammatory factors is interleukin-1 (IL-1), produced by activated macrophages, monocytes, fibroblasts, and other components of the innate immune system, such as dendritic cells. IL-1 is involved in various cellular activities, including cell proliferation, differentiation, and apoptosis (Seth L. al. Rev. Immunol. 2009. 27:621–68).
[0030] Cytokines from the IL-1 family are highly active and act as important mediators of inflammation, primarily associated with both acute and chronic inflammation (Sims J. et al., Nature Reviews Immunology 10, 89-102 (February 2010)). Overproduction of IL-1 is considered an initiator of some autoimmune and autoinflammatory diseases. Autoinflammatory diseases are characterized by recurrent and unexplained inflammation in the absence of autoantibodies, infection, or antigen-specific T lymphocytes.
[0031] The IL-1 superfamily of pro-inflammatory cytokines includes IL-1α, IL-1β, IL-18, and IL-36α,β,λ, which are produced as part of the host's innate immune response in response to pathogens and other cellular stressors. Unlike many other secretory cytokines that are processed and released through the standard cellular secretory region composed of the endoplasmic reticulum and Golgi apparatus, IL-1 family members lack the necessary leader sequences for endoplasmic reticulum entry and are therefore retained intracellularly after translation. Furthermore, IL-1β, IL-18, and IL-36α,β,λ are synthesized as procytokines, requiring proteolytic activation to become optimal ligands for binding to their homologous receptors on target cells.
[0032] In the case of IL-1α, IL-1β, and IL-18, it is now recognized that a multi-subunit protein complex called the inflammasome is responsible for activating the proforms of IL-1β and IL-18 and for the extracellular release of these cytokines. The inflammasome complex typically consists of sensor molecules such as NLR (Nucleotide-Oligerimisation Domain (NOD)-like receptors), adaptor molecules ASC (apoptosis-associated speckle-like proteins containing CARD (cysteine recruitment domain),) and procysteine-1. In response to various “danger signals,” including pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs), the subunits of the inflammasome oligomerize to form supramolecular structures within the cell. PAMPs can include molecules such as peptidoglycans, viral DNA or RNA, and bacterial DNA or RNA. On the other hand, DAMPs consist of a wide range of endogenous or exogenous sterile triggers, including monosodium urate crystals, silica, alum, asbestos, fatty acids, ceramides, cholesterol crystals, and β-amyloid peptide aggregates. Assembly of the inflammasome platform facilitates the autocatalysis of pro-cysteine protease-1 to produce highly active cysteine proteases responsible for the activation and release of pro-IL-1β and pro-IL-18. Therefore, the release of these highly inflammatory cytokines is achieved solely in response to inflammasome sensors that detect and respond to specific molecular danger signals.
[0033] In humans, 22 NLR proteins are divided into four NLR subfamilies based on their N-terminal domains. NLRA contains a CARD-AT domain, NLRB (NAIP) contains a BIR domain, NLRC (including NOD1 and NOD2) contains a CARD domain, and NLRP contains a pyrin domain. Several NLR family members are involved in inflammasome formation, including NLRP1, NLRP3, NLRP6, NLRP7, NLRP12, and NLRC4 (IPAF).
[0034] Two other structurally distinct inflammasome structures containing the PYHIN domain (proteins containing both pyrin and HIN domains), namely Absent in Melanoma 2 (AIM2) and IFNλ-induced protein 16 (IFI16) (Latz et al., Nat RevImmunol 2013 13(6) 397-311), act as intracellular DNA sensors. Pyrin (encoded by the MEFV gene) represents another type of inflammasome platform associated with pro-IL-1β activation (Chae et al., Immunity 34, 755-768, 2011).
[0035] The requirement to assemble an inflammasome platform to achieve the activation and release of IL-1β and IL-18 from monocytes and macrophages ensures that their generation is carefully planned through a two-step process. First, the cell must encounter a promoter ligand (such as the TLR4 receptor ligand LPS or an inflammatory cytokine such as TNFα), which leads to NFkB-dependent transcription of NLRP3, pro-IL-1β, and pro-IL-18. The newly translated procytokines remain intracellular and inactive unless the generating cell encounters a second signal leading to the activation of the inflammasome scaffold and the maturation of proceaspase-1.
[0036] In addition to proteolytic activation of pro-IL-1β and pro-IL-18, active caspase-1 also triggers a form of inflammatory cell death known as pyroptosis via the cleavage of gasdermin-D. Pyroptosis enables the externalization of mature forms of IL-1β and IL-18 along with the release of alarmin molecules (compounds that promote inflammation and activate innate and adaptive immunity), such as high-mobility group box 1 (HMGB1), IL-33, and IL-1α.
[0037] Although inflammasome activation appears to have evolved into a crucial component of host immunity against pathogens, the NLRP3 inflammasome is unique in its ability to activate in response to endogenous aseptic danger signals. Many such aseptic signals have been elucidated, and their formation is associated with specific disease states. For example, uric acid crystals found in patients with gout are potent triggers for NLRP3 activation. Similarly, cholesterol crystals found in patients with atherosclerosis can also promote NLRP3 activation. The understanding of the role of aseptic danger signals as NLRP3 activators has led to the involvement of IL-1 and IL-18 in a wide range of pathophysiological indications, including metabolic disorders, physiological disorders, inflammatory disorders, hematologic disorders, and immune disorders.
[0038] The best example of its association with human diseases is the following finding: mutations in the NLRP3 gene that lead to gain of function cause a series of autoinflammatory conditions collectively known as cryopyrin-associated periodic syndromes (CAPS), including familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), and neonatal onset multisystem inflammatory disease (NOMID) (Hoffman et al., Nat Genet. 29(3) (2001) 301-305). Similarly, sterile mediator-induced NLRP3 activation has been linked to a wide range of disorders, including joint degeneration (gout, rheumatoid arthritis, osteoarthritis), cardiovascular metabolism (type 2 diabetes, atherosclerosis, hypertension), central nervous system disorders (Alzheimer's disease, Parkinson's disease, multiple sclerosis), gastrointestinal disorders (Crohn's disease, ulcerative colitis), lung disorders (chronic obstructive pulmonary disease (COPD), asthma, idiopathic pulmonary fibrosis), and liver disorders (fibrosis, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis (NASH)). Furthermore, it is believed that NLRP3 activation promotes kidney inflammation and thus contributes to chronic kidney disease (CKD).
[0039] Current treatment options for diseases in which IL-1 contributes to pathogenesis include the IL-1 receptor antagonist anakinin, an Fc-containing fusion construct of the extracellular domain of the IL-1 receptor and IL-1 receptor accessory protein (linasip), and the anti-IL-1β monoclonal antibody canakinumab. For example, canakinumab is licensed for CAPS, tumor necrosis factor receptor-associated periodic syndrome (TRAPS), hyperimmunoglobulin D syndrome (HIDS) / mevalerate kinase deficiency (MKD), familial Mediterranean fever (FMF), and gout.
[0040] Several small molecules have been reported to inhibit the function of the NLRP3 inflammasome. Glibenclamide, for example, is a specific inhibitor of NLRP3 activation, although at micromolar concentrations that are impossible to achieve in vivo. Non-specific agents, such as parthenolide, Bay 11-7082, and 3,4-methylenedioxy-β-nitrostyrene, have been reported to impair NLRP3 activation, but are expected to have limited therapeutic efficacy due to their shared structural characteristics (composed of olefins activated by substitution with electron-withdrawing groups); this can lead to the undesirable formation of covalent adducts with thiol groups attached to proteins. Many natural products, such as β-hydroxybutyrate, sulforaphane, quercetin, and salvianolic acid, have also been reported to inhibit NLRP3 activation. Similarly, many effectors / modulators of other molecular targets have been reported to impair NLRP3 activation, including agonists of the G-protein-coupled receptor TGR5, epigliflozin (an inhibitor of sodium-glucose cotransport), the dopamine receptor antagonist A-68930, the serotonin reuptake inhibitor fluoxetine, the nonsteroidal anti-inflammatory drug fenamate, and the β-adrenergic receptor blocker nebivolol. The efficacy of these molecules as therapeutic agents for the chronic treatment of NLRP3-dependent inflammatory disorders remains to be established. A series of sulfonylurea-containing molecules have previously been identified as potent and selective inhibitors of pro-IL-1β post-translational processing (Perregaux et al., J Pharmacol. Exp. Ther. 299, 187-197, 2001). The example molecule CP-456,773 from this work was recently characterized as a specific inhibitor of NLRP3 activation (Coll et al., Nat Med 21.3 (2015): 248-255).

[0666] The following embodiments are provided as illustrative purposes and not as limiting, given that this disclosure has already been described.
[0667] It should be understood that all values presented in the examples are approximate and are subject to instrument and / or experimental variations.
[0668] Example 1. Exemplary synthesis of compound No. 10a The exemplary synthesis of compound No. 10a was carried out as shown in Schemes 1 and 2 and the following procedures. The overall synthetic route is a 7-step method, starting from commercially available or synthetically available starting materials. Scheme 1 details four steps of the preparation method. Compound No. 5a was prepared using the method described in Scheme 2.
[0669] Scheme 1: Synthetic route for the preparation of compound No. 10a Scheme 2: Synthetic route for the preparation of compound No. 5a (starting material) A. Materials Control Starting materials Two characterized starting materials were used in the preparation of compound No. 10a. 1,2,3,5,6,7-hexahydro-s-benzodiindene-4-amine (compound No. 7; CAS 63089-56-5) was a commercially available substance prepared to high specifications. The second starting material, compound No. 5a, was also prepared using the method described in Scheme 2. The starting materials (S)-tetrahydrofuran-2-carboxylic acid and 4-amino-1-methylpyrazole hydrochloride used to prepare compound No. 5a were commercially available substances.
[0670] All starting materials were fully synthetic, non-animal derived, and certified TSE-free. Starting materials were provided with the analytical certificate. All starting materials were validated and tested for use before proceeding to any step of the method.
[0671] Compound No. 5a (the starting material for step 4 of the preparation method) was prepared with very high purity (e.g., >99% as determined by HPLC). One parameter in the specification of Compound No. 5a is chiral purity. Due to toxicological issues related to the (R)-isomer, the specification for the enantiomer in Compound No. 5a was set at <100 ppm. This was achieved in part by using enantiomerically pure (S)-tetrahydrofuran-2-carboxylic acid, but during the preparation of Compound No. 5a, enantiomer excess was monitored at each stage, and both intermediates were recrystallized to ensure continuous chiral enrichment throughout the synthesis. The batches of Compound No. 5a conformed to this specification limit. The analysis of the batches of Compound No. 5a used in the preparation method is shown in Table A.
[0672] Table A: Analysis of Compound No. 5a Note: The identification of compound No. 5a in batches 1 and 2 was performed using... 1 H NMR, 13 Verification was performed using C NMR and mass spectrometry.
[0673] 1,2,3,5,6,7-Hexahydro-s-benzodiindene-4-amine (compound No. 7), the starting material for step 5 of the preparation method, was prepared with high purity (e.g., >98% as determined by HPLC). The analysis of compound No. 7 used in the preparation method is shown in Table B.
[0674] Table B: Analysis of Compound No. 7 Note: The identification of compound No. 7 in batch 1 was performed using... 1 Verification was performed using H NMR and mass spectrometry.

[0676] Table C: Analysis of Compound No. 6a ND = Not detected Note: This method was used for the identification of compound 6a in batches 1 and 2. 1 H NMR verification.
[0677] Compound No. 8 was prepared in the form of a toluene solution and used directly in step 6. The analysis is shown in Table D.
[0678] Table D: Analysis of Compound No. 8 Note: Compound 8 in batches 1 and 2 was used for identification. 1 H NMR verification.
[0679] Table E: Analysis of crude compound No. 9a Note: This method was used for the identification of compound 9a in batches 1 and 2. 1 H NMR verification.
[0680] In-process tests were performed during the synthesis of compound No. 10a to monitor the completion of conversion or drying at each step. The progress of each reaction was monitored using analytical techniques known in the art, such as HPLC, GC, GC-HS, MS, NMR, XRPD, and KF.
[0681] Step 4: Preparation of 1-(1-methyl-1H-pyrazol-4-yl)-1-[{(2S)-tetrahydrofuran-2-yl}methyl]sulfonylurea (compound No. 6a) Step 4 involves deprotecting the starting material (compound No. 5a) from its BOC using an aqueous hydrochloric acid solution. The reaction conditions for step 4 are as shown in Scheme 3.
[0682] Scheme 3: Step 4 - Preparation of compound No. 6a An aqueous solution of hydrochloric acid was prepared using water (1.1 v / v) and concentrated hydrochloric acid (5.0 equivalents, 1.1 v / v). Compound No. 5a (1 equivalent) was added in portions over approximately 2 hours. The mixture was stirred at room temperature for approximately 24 hours. After the reaction was complete, the mixture was cooled to 0 °C. Dichloromethane (2 v / v) was added, and the mixture was then alkalized by adding dropwise 46% sodium hydroxide solution (4.5 equivalents) over approximately 1 hour while maintaining the temperature at approximately 0 °C. The mixture was warmed to room temperature, and the pH was finely adjusted to pH 8 / 9 using 30% K₂CO₃ solution. The layers were separated, and the aqueous layer was extracted with dichloromethane (2 × 1 v / v) [water loss: ~0.5 mg / mL, 0.2% loss]. The combined dichloromethane extracts were washed with water (2 × 1 v / v), and the combined washes were further extracted with dichloromethane (1 × 2 v / v) [water loss: ~8.0 mg / mL, 2.3% loss]. The dichloromethane solution was concentrated to approximately 4 volumes (relative to compound No. 6). Heptane (6 volumes) was added dropwise, and the resulting slurry was aged at room temperature for approximately 1 hour. The solids were removed by filtration, and the filter cake was washed with heptane (1 × 1 volume) [mother liquor loss: ~2.6 mg / mL, 2.1% loss]. The collected solids were vacuum dried at 20°C for approximately 20 hours.
[0683] The exemplary yield of step 4 is 90%, with a purity of >98% as determined by HPLC.
[0684] Step 5: Preparation of 1,2,3,5,6,7-hexahydro-s-benzodiindene-4-isocyanate (compound No. 8) Step 5 involves treating 1,2,3,5,6,7-hexahydro-s-benzodiindene-4-amine (compound No. 7) with triphosgene to form the corresponding isocyanate, a toluene solution of 1,2,3,5,6,7-hexahydro-s-benzodiindene-4-isocyanate (compound No. 8). A concentrated solution of compound No. 8 (approximately 30% by weight) is used directly in step 6. The reaction conditions for step 5 are as shown in Scheme 5.
[0685] Scheme 5: Preparation of step 5-1,2,3,5,6,7-hexahydro-s-benzodiindene-4-isocyanate (compound No. 8) A solution of 1,2,3,5,6,7-hexahydro-s-benzodiindene-4-amine (compound No. 7; 1 equivalent) and triethylamine (2.05 equivalents) in toluene (6 volumes) was batch-treated over approximately 1 hour with a solution of cooled (0°C) triphosgene (0.34 equivalents) in toluene (21 volumes) while maintaining the temperature below 10°C. The mixture was then heated to room temperature. After confirming the reaction was complete, the mixture (which is a very thick slurry of triethylamine hydrochloride in toluene) was aged at room temperature for up to 24 hours. The slurry was filtered and the filtrate was collected. The reaction vessel was rinsed with toluene (8 volumes), and the filter cake was washed with the rinsing solution. The combined filtrate was then concentrated to ~4.5 volumes (relative to the input of compound No. 7). This solution can be stored at ambient temperature before use in step 6.
[0686] An exemplary weight-corrected yield of 1,2,3,5,6,7-hexahydro-s-benzodiindene-4-isocyanate (compound No. 8) was approximately 85%, with a purity of >98% as determined by HPLC.
[0687] Step 6: Preparation of 1-(1,2,3,5,6,7-hexahydro-s-benzodiindene-4-yl)-3-[(1-methyl-1H-pyrazol-4-yl)({[(2S)-tetrahydrofuran-2-yl]methyl})aminosulfonyl]urea sodium salt IPA solvate (compound No. 9a) Step 6 is the final synthetic step in preparing compound No. 9a prior to final recrystallization to prepare the desired polymorphic form. This reaction is a sulfonylurea formation reaction involving the treatment of a tetrahydrofuran solution of 1-(1-methyl-1H-pyrazol-4-yl)-1-[{(2S)-tetrahydrofuran-2-yl}methyl]sulfonylurea (compound No. 6a) with a toluene solution of 1,2,3,5,6,7-hexahydro-s-benzodiindene-4-isocyanate (compound No. 8) in the presence of sodium hydroxide. The crude compound No. 9a is isolated as an IPA solvate of the monosodium salt. The reaction conditions for step 6 are as shown in Scheme 6.
[0688] Scheme 6: Step 6 - Preparation of crude compound No. 9a While maintaining room temperature, a tetrahydrofuran solution (10 volumes) of compound No. 6a (1.0 equivalent) was treated dropwise with concentrated NaOH (46.7 wt%, 1.01 equivalent). The solution was aged at room temperature for approximately 0.5 hours. Then, a toluene solution (1.01 equivalent) of compound No. 8 was added over approximately 0.5 hours. After the reaction was complete, the mixture was concentrated to remove the tetrahydrofuran (approximately 8 volumes of solvent). Isopropanol (IPA; 10 volumes) was added, and the mixture was aged for approximately 0.5 hours. Then, methyl tert-butyl ether (MTBE; 5 volumes) was added, and the mixture was aged for approximately 0.5 hours. After confirming satisfactory conversion, the solid was removed by filtration, and the filter cake was washed with 2:1 IPA-MTBE (6 volumes). The resulting solid was dried under vacuum at 20–40 °C.
[0689] The exemplary weight-corrected yield of crude compound No. 9a is approximately 90%, with a purity of >99% as determined by HPLC.
[0690] Step 7: Preparation of 1-(1,2,3,5,6,7-hexahydro-s-benzodiindene-4-yl)-3-[(1-methyl-1H-pyrazol-4-yl)({[(2S)-tetrahydrofuran-2-yl]methyl})aminosulfonyl]urea sodium salt monohydrate (compound No. 10a) The final step in the preparation of compound No. 10a is the recrystallization of crude compound No. 9a from tetrahydrofuran / water / ethyl acetate using n-heptane as the antisolvent. This recrystallization method can be used to improve the purity of compound No. 10a, but the primary purpose is to control the polymorphic form (form 3) of compound No. 10a used in clinical trials to be a monohydrate. The reaction conditions for step 7 are shown in Scheme 7.
[0691] Scheme 7: Step-by-step preparation of purified compound No. 10a The crude compound No. 9a was dissolved in tetrahydrofuran (THF; 4 volumes relative to the content). The solution was filtered through diatomaceous earth and washed with THF (2 × 1 volume). This solution was then subjected to final fine filtration and concentrated to 3 volumes. Ethyl acetate (15 volumes) was added and the mixture was concentrated to 10 volumes. Ethyl acetate (10 volumes) and water (0.2 volumes) were then added, and the mixture was heated to 45°C, then inoculated (1% seed crystals relative to the content) and aged for up to 1 hour. The mixture was then cooled to 30°C over 0.5–1 hour. Heptane (5 volumes) was added. The resulting solid was collected by filtration and washed with 4:1 ethyl acetate-heptane (4 volumes) containing 1% v / v water (relative to ethyl acetate). The solid was dried in a vacuum oven at 20°C by purging with N2.
[0692] The exemplary weight-corrected recovery of compound No. 10a is approximately 90%, and the purity is >99% as determined by HPLC.
[0693] Example 2. Properties of compound No. 10a Compound No. 10a is a white to off-white crystalline powder. It has a single stereocenter. Compound No. 10a is a confirmed single enantiomer with the (S)-configuration.
[0694] Polymorphism: Polymorphism screening of compound No. 10a revealed one hygroscopic amorphous form and three polymorphic forms. During characterization, a metastable anhydrous form 1 was recovered from GVS analysis. Furthermore, a dihydrate form 2 was prepared from the amorphous compound at 25°C / 97% RH and 40°C / 75% RH. After storage at 60°C / 75% RH, the amorphous compound converted to a monohydrate form 3. A new metastable anhydrous form 9 was identified upon dehydration of form 3. Compound No. 10a forms solvates with certain alcohol solvents, most notably the IPA solvate, which was separated as an intermediate during preparation and then further processed into the final form.
[0695] Form 2 (dihydrate) and Form 3 (monohydrate) have comparable solid-state properties. The monohydrate (form 3) was prepared as described in Example 1. It exhibits a single crystalline / polycrystalline form, namely the sodium salt monohydrate (form 3).
