چکیده
In the title compound, C15H18N2O5, the meth-oxy-phenyl ring makes a dihedral angle of 84.70 (12)° with the mean plane of the tetra-hydro-pyrimidin-2(1H)-one ring. Both the pyran and tetra-hydro-pyrimidin-2(1H)-one rings have distorted envelope conformations with the carboxyl-ate-substituted C atom as the flap. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming zigzag chains propagating along [010], which enclose R (2) 2(8) ring motifs. The chains are linked by C-H⋯π inter-actions, forming a two-dimensional network parallel to (100).
