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