5-Acetyl-4-(2-chloro­phen­yl)-6-methyl-3,4-dihydro­pyrimidin-2(1H)-one

In the title mol­ecule, C(13)H(13)ClN(2)O(2), the heterocyclic ring adopts a flattened boat conformation with the plane through the four coplanar atoms making a dihedral angle of 89.16 (5)° with the benzene ring, which adopts an axial orientation. The carbonyl, acetyl and methyl groups each have an equatorial orientation. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds lead to a tape motif. The H atoms of the methyl group at position 6 are disordered over two positions of opposite orientation.
