Abstract
The title compound, C22H19NO6, 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.
