Procedure

Ethanol (6 mL) and tetrahydrofuran (72 mL) were added to 5-acetyl-2-benzyloxy-N-[3,5-bis(trifluoromethyl)phenyl]benzamide (602 mg, 1.25 mmol) and 5% palladium-carbon (60 mg), and the mixture was hydrogenated at room temperature for 30 minutes. After the insoluble matter was filtered off, the solvent was evaporated under reduced pressure and the residue was recrystallized from n-hexane-ethyl acetate to give the title compound (230 mg, 47.0%) as a white solid.
