Description

[Technical Field]

[0001] The present invention relates to the crystalline form of (R)-4-(1-(3-methyl-2-((4-(trifluoromethyl)benzyl)oxy)butanamide)cyclopropyl)benzoic acid and a method for producing the same. The present invention also relates to compositions, such as pharmaceutical compositions, that contain the crystalline form of (R)-4-(1-(3-methyl-2-((4-(trifluoromethyl)benzyl)oxy)butanamide)cyclopropyl)benzoic acid, and therapeutic uses of the crystalline form. [Background technology]

[0002] International Publication No. 2021 / 069927 discloses the compound of formula (1) below, (R)-4-(1-(3-methyl-2-((4-(trifluoromethyl)benzyl)oxy)butanamide)cyclopropyl)benzoic acid, as an antagonist of prostaglandin E2 receptor 4 (EP4).

[0003] [ka]

[0004] Prostaglandins (PGs) are small molecule (approximately 400 Da) products produced by cyclooxygenase (COX; constitutively active COX1 and inducible COX2) and PG synthase acting on arachidonic acid (AA) with minimal contribution from the isoprostane pathway. Prostaglandin E2 (PGE2) is the major COX product in myeloid and stromal cells, and its levels are determined by the balance between synthesis and degradation mediated by 15-hydroxyprostaglandin dehydrogenase (15-PGDH). PGE2 has four receptors (EP1-EP4), which are present on multiple cell types including macrophages, monocytes, platelets, sensory neurons, and cells in the gastrointestinal tract, kidneys, thymus, heart, lungs, and uterus. These receptors drive a wide range of pharmacological effects, mediating nociception, various aspects of nerve signaling, hematopoiesis, blood flow regulation, renal filtration and blood pressure, mucosal integrity regulation, vascular permeability, smooth muscle function, and both pro-inflammatory (vasodilation and recruitment and activation of mast cells, macrophages, and neutrophils) and immunosuppressive immune functions. Functional PGE2 antagonism has therapeutic potential in a wide range of disease settings.

[0005] Different crystalline forms of compounds can result in different properties in terms of solubility, elution rate, filterability, hygroscopicity, fluidity, and stability.

[0006] (R)-4-(1-(3-methyl-2-((4-(trifluoromethyl)benzyl)oxy)butanamide)cyclopropyl)benzoic acid is available in multiple crystalline forms as well as amorphous forms. It has also been found that these forms can exist. Many of these forms are undesirable from the standpoint of producing pharmaceutically acceptable compositions.

[0148] A method for producing (R)-4-(1-(3-methyl-2-((4-(trifluoromethyl)benzyl)oxy)butanamide)cyclopropyl)methyl benzoate is disclosed in International Publication No. 2021 / 069927.

[0149] Saponification In a 5L jacketed reactor equipped with a mechanical stirrer, thermometer, dropping funnel, and reflux partition with condenser, (R)-4-(1-(3-methyl-2-((4-(trifluoromethyl)benzyl)oxy)butanamide)cyclopropyl)methyl benzoate (145.2 g; 0.32 mol; 1.0 equivalent) was added to isopropanol (300 mL; 2.0 rel. vol.), and 33% sodium hydroxide aqueous solution (58.1 g; 0.48 mol; 1.5 equivalents) was added via a dosing funnel. Purified water (300 mL; 2 rel. vol.) was added, and the solution was heated to 60±5°C. The solution was stirred at 60±5°C for 4 hours.

[0150] Without organic solvents, the reaction proceeded very slowly, taking 24 hours to reach complete conversion in water. The reaction proceeded well in a mixture of water with methanol, tetrahydrofuran, or isopropanol.

[0151] The reaction temperature was investigated through screening experiments. The reaction was carried out at 20, 40, and 60°C. Complete conversion was observed within 1-2 hours at 60°C and within 4.5 hours at 40°C, but it took several days at 20°C. The in situ purity profile at the reaction endpoint was similar at all temperatures. Therefore, it is preferable to use a reaction temperature of 55-65°C, or approximately 60°C, in this process.

[0152] Isolation A 1N citric acid solution was prepared by dissolving 198.8 g of citric acid in 510 mL of purified water and 510 mL of isopropanol. The reaction mixture was adjusted to pH 3.5 by adding 1105 g of this 1N citric acid solution. The mixture was stirred at 60°C for a further 20 minutes to obtain a concentrated suspension.

[0153] Next, heat the mixture to 80°C to dissolve the entire volume, then add purified water (1750 mL; 12.0 (rel.vol.) was added within 1 hour. Crystallization occurred after adding one-third of the water. The suspension was stirred at 80°C for a further 16 hours, then cooled to 20°C over 3.5 hours. After stirring for another hour at 20°C, the suspension was filtered. The cake was rinsed three times with purified water (3 × 300 mL; 3 × 2.0 rel.vol.) and air-dried to obtain the crystalline form of the present invention as a white powder (125.5 g; 96%). HPLC purity: 99.9 area%.

[0154] The isolation of the crystalline form of the present invention was optimized.

[0155] Initially, acidification was carried out using an aqueous hydrochloric acid solution, but this was replaced with an aqueous citric acid solution to prevent the formation of isopropyl chloride. Therefore, it is preferable to perform acidification using citric acid.

[0156] To prevent the compound of formula (1) from crystallizing during the acidification process, it is preferable to maintain the reaction mixture at a temperature of 60-70°C during the acidification step.

[0157] After acidifying the reaction mixture with isopropanol / water, water was added, and the compound of formula (1) precipitated.

[0158] If water is added at a temperature significantly below 80°C, the compound of formula (1) may precipitate too quickly, potentially resulting in an unagitable suspension or a rubber ball-like substance. Therefore, it is preferable to provide the solution at a temperature of 75-85°C (approximately 80°C). Furthermore, it is preferable to maintain the solution at a temperature of 75-85°C, or approximately 80°C, while adding water.

[0159] This optimized procedure allowed the crystalline form of the present invention to be obtained directly from the reaction mixture in high purity.

[0160] Characteristic evaluation Table 2 shows a list of XRPD peaks for the aforementioned crystal form. Figure 1 shows the XRPD spectrum of the aforementioned crystal form. Figure 2 shows the TGA and DSC plots of the aforementioned crystal form. Figure 3 shows the FT-IR spectrum of the aforementioned crystal form. Figure 4 shows the NMR spectrum of the aforementioned crystal form.

[0161] The TGA thermogram of the aforementioned crystal form showed that the mass did not decrease prior to decomposition at approximately 280°C. 1 The 1H-NMR spectrum was consistent with the proposed structure, and no residual solvent was observed. 1 Since no solvent was detected by 1H-NMR and no weight loss was observed by TGA, the crystalline form is considered to be an anhydrous form.

[0162] [Table 2]

[0163] Example 2 In a calorimeter reactor (RC-1), the reaction described in Example 1 was carried out on a 28g scale using the starting material (R)-4-(1-(3-methyl-2-((4-(trifluoromethyl)benzyl)oxy)butanamide)cyclopropyl)methyl benzoate. The reaction at 60°C following the addition of sodium hydroxide generated 100.3 kJ / mol of heat, which corresponds to an adiabatic temperature rise of 8.4 K. Acidification with citric acid solution at 60°C generated 65.0 kJ / mol of heat, which corresponds to an adiabatic temperature rise of 2.2 K. Crystallization occurred during the addition of water at 80°C, generating 222.2 kJ / mol of heat, which corresponds to an adiabatic temperature rise of 3.8 K. This process is safe to carry out on a large scale.

[0164] Example 3 The crystalline form was packed into a double-lined antistatic LDPE bag, secured with cable ties, and placed inside a sealed HDPE drum.

[0165] The stability of the crystalline form of the present invention was evaluated under long-term conditions of 25°C / 60% relative humidity (RH) for 18 months, and under accelerated conditions of 40°C / 75%RH for 6 months.

[0166] Detailed data on the stability of the crystal form is shown in Table 3 (40°C / 75%RH) and Table 4 (25°C / 60%RH).

[0167] [Table 3]

[0168] [Table 4]

[0169] Example 4 DVS analysis was performed on the crystalline form of the present invention. The DVS adsorption and desorption plots are shown in Figure 5. The DVS isothermal plot is shown in Figure 6.

[0170] During drying in DVS at 0% RH, a mass loss of 0.03 wt% was observed. Subsequently, sustained uptake was observed as RH increased, reaching 0.06 wt% at 70% RH. Above 70% RH, the uptake became steeper, increasing to 0.16 wt% at 95% RH. The total mass uptake was less than 0.2 wt%, and therefore, the crystalline form of the present invention does not meet the criteria of hygroscopicity according to the European Pharmacopoeia. The second adsorption and desorption cycles showed similar behavior. Therefore, the cycle is reversible and reproducible.

[0171] XRPD was performed on the sample after DVS analysis to confirm that the sample was the crystalline form of the present invention.

[0172] Comparative Example Comparative crystalline forms of the compound of formula (1) were prepared according to the following method.

[0173] 500 mg of the compound of formula (1) was treated with dimethyl sulfoxide (DMSO) (3 Vol) at room temperature to obtain a clear solution. Water (3 Vol) was added to this solution. The resulting suspension was vigorously stirred at room temperature for 2 hours. A precipitate formed. This substance was isolated by Buchner filtration, washed with an excess of water, and dried by vacuum for 1 hour. The sample was then further dried in a vacuum oven (RT) for 2 hours.

[0174] Table 5 provides a list of XRPD peaks for the comparative crystal form. Figure 7 shows the XRPD spectrum of the comparative crystal form. Figure 8 shows the TGA and DSC plots of the comparative crystal form. 1 The 1H-NMR spectrum was consistent with the proposed structure, and residual DMSO was observed.

[0175] This comparative form is the crystalline DMSO solvate. The stability of the comparative form was evaluated under accelerated conditions of 40°C / 75%RH, and it was found to be unstable after 7 days of static storage. VT-XRPD analysis also showed that the comparative crystalline form is unstable above 100°C. The comparative crystalline form is slightly hygroscopic.
