反应详情

To benzaldehyde (26.1 g, 25.0 mL, 0.246 mol, 1.21 equiv) in toluene (100 mL) was added 2-methoxyaniline (25.1 g, 23.0 mL, 0.204 mol, 1.00 equiv). The reaction mixture was heated to reflux with azeotropic removal of water with a Dean-Stark trap for 12 h. The reaction mixture was concentrated and dried under high vacuum to afford (E)-N-benzylidene-2-methoxyaniline as a yellow oil (43.0 g, >99% yield).
