Deskripsi
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).
