実験手順
To a solution of 1-(2,3,6-trifluorophenyl)ethanone (1.74 g, 10 mmol) in THF (10 mL) was added methyl magnesium bromide (7 mL, 21 mmol) at 0° C. The mixture was stirred at 0° C. for 1 hour. The reaction was quenched by addition of saturated aqueous ammonium chloride and was then extracted with EtOAc. The combined organic layers were washed with water, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel to afford 2-(2,3,6-trifluorophenyl)propan-2-ol. (74).
