실험 절차

5N Aqueous sodium hydroxide (0.1 mL) was added to a solution of 2-acetoxy-5-chloro-N-({[3,5-bis(trifluoromethyl)phenyl]carbamoyl}methyl)benzamide (83.7 mg, 0.17 mmol) in methanol/tetrahydrofuran (2 mL+1 mL), and the mixture was stirred at room temperature for 20 minutes. The reaction mixture was poured into diluted hydrochloric acid and extracted with ethyl acetate. After the ethyl acetate layer was washed with water and brine, dried over anhydrous sodium sulfate, the residue obtained by evaporation of the solvent under reduced pressure was purified by column chromatography on silica gel (n-hexane:ethyl acetate=2:1) and washed with n-hexane under suspension to give the title compound (47.7 mg, 63.7%) as a white crystal.
