実験手順

A solution of Sodium hydroxide (1.904 mL, 3.81 mmol) was added in one portion to a stirred solution of ethyl 4-[4-(2-adamantylcarbamoyl)-5-tert-butyl-pyrazol-1-yl]-3-methyl-benzoate (Intermediate#113) (353 mg, 0.76 mmol) in methanol (6 mL). The resulting suspension was stiffed at 20° C. for 16 hours. The resulting mixture was evaporated to remove the methanol and washed with ether (20 mL). The reaction mixture was acidified with 2M HCl. The precipitate was collected by filtration, washed with water (10 mL) and dried under vacuum to afford 4-[4-(2-adamantylcarbamoyl)-5-tert-butyl-pyrazol-1-yl]-3-methyl-benzoic acid (266 mg, 80%) as a white solid.
