摘要

In the title compound, C15H18N2O5, the meth#173;oxy#173;phenyl ring makes a dihedral angle of 84.70#8197;(12)#176; with the mean plane of the tetra#173;hydro#173;pyrimidin-2(1H)-one ring. Both the pyran and tetra#173;hydro#173;pyrimidin-2(1H)-one rings have distorted envelope conformations with the carboxyl#173;ate-substituted C atom as the flap. In the crystal, mol#173;ecules are linked via pairs of N#8212;H#8943;O hydrogen bonds, forming zigzag chains propagating along 010, which enclose R22(8) ring motifs. The chains are linked by C#8212;H#8943;#960; inter#173;actions, forming a two-dimensional network parallel to (100).
