実験手順: To a solution of (2-bromo-5-fluorophenyl)acetic acid (1.29 g, 5.54 mmol) in tetrahydrofuran (15 mL) was added lithium aluminum hydride (210 mg, 5.54 mmol) at 0° C. The mixture was warmed to room temperature and stirred for 3 h. After cooling to 0° C., the reaction mixture was quenched by the addition of 2N hydrochloric acid (30 mL), extracted with diethyl ether (200 mL). The organic layer washed with water (50 mL) and brine (50 mL) dried over magnesium sulfate, and evaporated. The residue was purified by column chromatography on silica gel (40 g) eluting with hexane/ethyl acetate (5/1) to afford 247 mg (20%) of the title compound as colorless oil: After cooling to 0° C. the reaction mixture was quenched by the addition of 2N hydrochloric acid (30 mL) extracted with diethyl ether (200 mL) The organic layer washed with water (50 mL) and brine (50 mL) dried over magnesium sulfate evaporated The residue was purified by column chromatography on silica gel (40 g) eluting with hexane/ethyl acetate (5/1)
