ABSTRACT
In the title compound, C14H13N3O4, the pyran ring adopts an envelope conformation with the methine C atom as the flap. The dihedral angle between the benzene and hydro-pyridine rings is 29.33 (3)°. The methyl-amine C atom deviates from the plane of its attached ring by 0.380 (5) Å and an intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. In the crystal, weak C-H⋯O hydrogen bonds and aromatic π-π stacking inter-actions [centroid-centroid distances vary from 3.6529 (10) to 3.6872 (10) Å] link the mol-ecules, generating a three-dimensional network.
