反应详情

To a solution of 3-fluoro-2-methoxy-benzaldehyde (3.41 g, 22.1 mmol) in methanol (20 mL) is slowly added portionwise sodium borohydride (1.00 g, 26.6 mmol). The reaction is stirred at room temperature under nitrogen overnight. The reaction is diluted with diethyl ether, washed with water twice, dried over anhydrous sodium sulfate, filtered, and concentrated to afford 3.02 g (87%) of the title compound as a clear colorless oil. 1H NMR (400 MHz, CDCl3) δ 7.09-6.92 (m, 3H), 4.65 (d, 2H), 3.97 (s, 3H), 2.14 (t, 1H, OH).
