چکیده
In the title compound, C17H22N2O6, the di-hydro-pyrimidine ring adopts a flattened boat conformation. The dihedral angle between the benzene ring and the mean plane of the di-hydro-pyrimidine ring is 75.25 (6)°. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif which are linked through N-H⋯O and weak C-H⋯O hydrogen bonds. These, together with π-π ring inter-actions [centroid-centroid distance = 3.7965 (10) Å], give an overall three-dimensional structure.
