5-Acetyl-4-(4-methoxy-phen-yl)-6-methyl-3,4-dihydro-pyrimidin-2(1H)-one.

In the title mol-ecule, C(14)H(16)N(2)O(3), the heterocyclic ring adopts a flattened boat conformation, and the plane through its four coplanar atoms makes a dihedral angle of 89.65 (7)° with the benzene ring. The non-H atoms of the carbonyl, acetyl and methyl groups are nearly coplanar with the attached heterocyclic ring. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds are present in the crystal structure.
