反应详情

To a mixture of (E)-3-(4-fluorophenoxy)benzaldehyde oxime (3.0 g, 12.9 mmol, 1.0 eq) in ethanol, was added Raney nickel (300 mg, 10% wt/wt) followed by aqueous ammonia (10% in volume). The reaction mixture was stirred at ambient temperature under hydrogen pressure for 4 h, before being filtered. The filtrate was concentrated under high vacuum to obtain the desired compound (1.8 g, 64%). 1H NMR (400 MHz, DMSO-d6) δ 7.30-7.17 (m, 3H), 7.07-6.80 (m, 4H), 6.79-6.76 (t, 1H), 3.67 (s, 1H). MS (ESI): 218.2 (M+H)+.
