title: 5-Acetyl-4-(2-chloro-phen-yl)-6-methyl-3,4-dihydro-pyrimidine-2(1H)-thione.
abstract: In the title mol-ecule, C(13)H(13)ClN(2)OS, the heterocyclic ring adopts a flattened boat conformation with the plane through the four coplanar atoms making a dihedral angle of 85.6 (1)° with the benzene ring, which adopts an axial orientation. The thionyl, acetyl and methyl groups all have equatorial orientations. Inter-molecular N-H⋯O, N-H⋯S and C-H⋯S hydrogen bonds are found in the crystal structure. A weak C-H⋯π inter-action involving the benzene ring also occurs.
