Ethyl 4-(4-chloro-phen-yl)-6-methyl-2-thioxo-1,2,3,4-tetra-hydro- pyrimidine-5-carboxyl-ate

Abstract

In the title compound, C14H15ClN2O2S, the tetra-hydro-pyrimidine ring adopts a twisted boat conformation with the carbonyl group in an s-trans conformation with respect to the C=C double bond of the six-membered tetra-hydro-pyrimidine ring. The mol-ecular conformation is determined by an intra-molecular C- H⋯π inter-action. The crystal structure is further stabilized by inter-molecular N- H⋯O mol-ecular chains and centrosymmetric N- H⋯S dimers.
