반응 단계

Methyl magnesium bromide (5.3 mL, 0.075 mol) was added to a stirred solution of 1-(5-bromopyridin-3-yl)ethanone (1.0 g, 0.05 mol) in tetrahydrofuran (20.0 mL), cooled to 0° C. and the resulting mixture was allowed to warm to room temperature and stirred for 1.5 h. The reaction mixture was quenched with 1N hydrochloric acid (20 mL) and extracted with ethyl acetate (2×75 mL). The combined organic layers were dried over sodium sulphate and concentrated under vacuum to afford the crude compound which was purified by column chromatography to obtain 2-(5-bromopyridin-3-yl)propan-2-ol. MS (M+1): 217.1.
