This compound has unique chemical properties. The synthetic route is as follows. Recommanded Product: 147149-98-2
POCl3 (98.85 mg, 0.65 mmol) was added to a mixture of 1-(2-methylimidazo[1,2-a]pyridin-5-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid (100 mg, 0.32 mmol), 2-(trifluoromethyl)pyridin-4-amine (52.26 mg, 0.32 mmol), pyridine (127.49 mg, 1.61 mmol) in CH2Cl2 (3 mL) at rt. The reaction mixture was stirred at room temperature for 1 h. The reaction mixture was quenched with 20 mL sat. K2CO3 aq, and extracted with CH2Cl2 (20 mL*3). The organic layer was separated and concentrated under reduced pressure. It was purified by preparative high-performance liquid chromatography (35% to 65% (v/v) CH3CN and H2O with 0.05% ammonia hydroxide). The pure fractions were collected and the organic solvent was concentrated under reduced pressure. The aqueous layer was lyophilized to dryness to give the desired product as a white solid. (80 mg, purity: 99.5%, yield: 54.3%). LCMS (ESI) m/z M+1: 454.9. 1H NMR (400 MHz, DMSO-d6) delta ppm 2.32 (s, 3H), 7.08 (s, 1H), 7.32 (d, J=7.06 Hz, 1H), 7.41 (dd, J=9.04, 7.28 Hz, 1H), 7.75 (d, J=9.04 Hz, 1H), 7.94 (dd, J=5.73, 1.76 Hz, 1H), 8.21 (d, J=1.76 Hz, 1H), 8.65 (s, 1H), 8.69 (d, J=5.29 Hz, 1H), 11.29 (s, 1H).
