実験手順
To a solution of ethyl 4-[3-(trifluoromethoxy)benzyl]benzoate (Preparation 149, 950 mg, 2.93 mmol) in THF/MeOH/water (4:3:2, 27 mL) was added lithium hydroxide (246 mg, 5.86 mmol) and the mixture was stirred at room temperature for 4 hours. The mixture was concentrated in vacuo and acidified with 1M hydrochloric acid solution. The resulting precipitate was filtered off and dried to give the title compound as a white solid (600 mg, 69%).
