Reaction Conditions

Reaction Steps

2M aqueous sodium hydroxide (2.446 mL, 4.89 mmol) was added in one portion to methyl 4-[4-(2-adamantylcarbamoyl)-5-ethylsulfanyl-pyrazol-1-yl]benzoate (Intermediate#99) (430 mg, 0.98 mmol) in methanol (20 mL). The resulting mixture was stirred at 20° C. for 18 hours. The reaction mixture was concentrated, diluted with water (50 mL) and adjusted to pH 3 with 2M HCl. The precipitate was collected by filtration, washed with water (20 mL) and dried under vacuum to afford 4-[4-(2-adamantylcarbamoyl)-5-ethylsulfanyl-pyrazol-1-yl]benzoic acid (383 mg, 92%) as a white solid.
