5-Acetyl-4-(4-chlorophenyl)-6-methyl-3,4-dihydropyrimidine-2(1H)-thione

In the title molecule, C13H13ClN2OS, the heterocyclic ring adopts a flattened boat conformation, and the plane through the four coplanar atoms makes a dihedral angle of 87.92 (10)° with the benzene ring. The thione, acetyl and methyl groups have equatorial orientations with respect to the attached heterocyclic ring. The chlorophenyl group has an axial orientation. Intermolecular N—H...O, N—H...S and C—H...O hydrogen bonds are found in the crystal structure
