Under an argon atmosphere, a solution of 2,5-dimethoxyphenethylamine (3.175 g) in benzene (4 mL) was added with stirring to a suspension of benzaldehyde (1.86 g) and magnesium sulfate (3.89 g) in benzene (10 mL). An exothermic reaction took place, followed by further stirring overnight. After the reaction was complete, the reaction liquid was filtered and the filtrate was concentrated under reduced pressure to obtain 2-(2,5-dimethoxyphenyl)-N-[(1E)-phenylmethylene]ethanamine (4.72 g).
