摘要

In the title compound, C15H18N2O5, the meth­oxy­phenyl ring makes a dihedral angle of 84.70 (12)° with the mean plane of the tetra­hydro­pyrimidin-2(1H)-one ring. Both the pyran and tetra­hydro­pyrimidin-2(1H)-one rings have distorted envelope conformations with the carboxyl­ate-substituted C atom as the flap. In the crystal, mol­ecules are linked via pairs of N—H⋯O hydrogen bonds, forming zigzag chains propagating along [010], which enclose R22(8) ring motifs. The chains are linked by C—H⋯π inter­actions, forming a two-dimensional network parallel to (100).
