title: 1-(4-Chloro-phen-yl)-4,4,6-trimethyl-3,4-dihydro-pyrimidine-2(1H)-thione.
abstract: The dihydro-pyrimidine ring of the title compound, C(13)H(15)ClN(2)S, adopts an envelope conformation with five almost coplanar atoms (r.m.s. deviation = 0.054 Å) and the C atom bearing the two methyl substituents deviating from this plane by 0.441 (2) Å. The best plane through the five almost coplanar atoms forms a dihedral angle of 89.56 (5)° with the benzene ring. The crystal packing is characterized by centrosymmetric dimers connected by pairs of N-H⋯S hydrogen bonds.
