摘要：

The title compound, C-22H19NO6, was synthesized by the reaction of 4-hydroxycoumarin and ethyl 4'-methoxy-2-cyanocinnamate in the presence of triethylbenzylammonium chloride in an aqueous medium. In the crystal structure, the amino group is involved in both intra- and intermolecular N-H...O hydrogen bonds.
