In the title compound, C17H22N2O6, the dihydropyrimidine ring adopts a flattened boat conformation. The dihedral angle between the benzene ring and the mean plane of the dihydropyrimidine ring is 75.25 (6)°. In the crystal, molecules are linkedviapairs of N—H...O hydrogen bonds, forming inversion dimers with anR22(8) ring motif which are linked through N—H...O and weak C—H...O hydrogen bonds. These, together with π–π ring interactions [centroid–centroid distance = 3.7965 (10) Å], give an overall three-dimensional structure.
