✦ Synopsis

The asymmetric unit of the title compound, C 16 H 19 Cl 2 N 3 OS, contains two crystallographically independent molecules, which have almost identical conformations. The dihydropyrimidine ring adopts a boat conformation in both molecules. N-HÁ Á ÁO and N-HÁ Á ÁS hydrogen bonds stabilize the crystal packing. The crystal is an inversion twin.
