反应详情

A solution of (R)-1,1,1-trifluoropropan-2-ol (212 mg) in N,N-dimethylformamide (1.5 ml) was cooled to 0° C., sodium hydride (74 mg, 60 wt. % oil dispersion) and 3-(bromomethyl)phenyl boronic acid (100 mg) were sequentially added thereto, and the mixture was stirred at room temperature for 2 hours. To this reaction mixture were added water and an 1M aqueous solution of hydrochloric acid, and the mixture was extracted with ethyl acetate. This organic layer was washed with water and a saturated aqueous solution of sodium chloride, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure to give the titled compound (147 mg).
