실험 절차

Add sodium borohydride (95 mg, 2.44 mmol) to a solution of 1-(3-nitro-5-(trifluoromethyl)phenyl)ethanone (570 mg, 2.44 mmol) in methanol (5 mL), stir the mixture for 15 min at ambient temperature. Quench the reaction with water, adjust pH=7 with 1N hydrochloric acid, extract with ethyl acetate (50 mL×3), combine the organic layers, wash with brine, dry over sodium sulfate. Concentrate under reduced pressure to provide the crude product. Purify by flash chromatography (silica gel, EtOAc:PE=1:10) to afford the title compound (520 mg, 91.2%).
