Abstract
In the title compound, C(19)H(17)NO(6), the dihedral angle between the 2H-chromene ring system and benzene ring is 5.34 (6)°. A short intra-molecular C-H⋯O contact occurs. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, generating C(8) chains propagating in [010]. The chains are linked by C-H⋯O inter-actions and the packing also exhibits π-π stacking inter-actions between benzene and pyran rings, with a centroid-centroid distance of 3.676 (9) Å.Entities:
