Procedure

A mixture of bis(2,4-dimethoxybenzyl)amine (8 g), ethyl 3-ethoxy-3-iminopropanoate (8.02 g), acetic acid (1.44 mL) and ethanol (420 mL) was refluxed overnight. 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 (17 g).
