Participants

Reaction Steps

Methyl 4-[5-propylsulfanyl-4-[3-[2-(trifluoromethyl)phenyl]pyrrolidine-1-carbonyl]pyrazol-1-yl]benzoate (Intermediate #6) (177 mg, 0.34 mmol) was stirred at ambient temperature for 18 h in a mixture of methanol (5 mL) and 2M sodium hydroxide (0.855 mL, 1.71 mmol) for 18 h. The reaction mixture was evaporated to remove the methanol. The residue was dissolved in water (20 mL) and acidified to pH4 with 2M HCl. The resulting white precipitate was recovered by filtration, washed with water and dried under vacuum to give the title compound as a white solid (116 mg, 68%).
