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 hydropyridine rings is 29.33 (3)°. The methylamine C atom deviates from the plane of its attached ring by 0.380 (5) Å and an intramolecular N—H...O hydrogen bond closes anS(6) ring. In the crystal, weak C—H...O hydrogen bonds and aromatic π–π stacking interactions [centroid–centroid distances vary from 3.6529 (10) to 3.6872 (10) Å] link the molecules, generating a three-dimensional network.
