【 摘 要 】

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 linked via pairs of N—H⋯O hydrogen bonds, forming inversion dimers with an R22(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.
