A solution of 2,4-dimethoxybenzylamine (8.98 mL) and 2,4-dimethoxybenzaldehyde (9.94 g) in ethanol (200 mL) was stirred at room temperature for 2 hr. To the reaction mixture was added sodium triacetoxyborohydride (20.3 g), and the mixture was stirred at room temperature for 1 hr. To the reaction mixture was added water, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (8 g).
