title: Crystal structure of ethyl 4-(2-fluoro-phen-yl)-6-methyl-2-sulfanyl-idene-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.
abstract: The title compound, C14H15FN2O2S, crystallizes with two mol-ecules in the asymmetric unit. In each mol-ecule, the pyrimidine ring adopts a sofa conformation with the sp (3)-hybridized C atom forming the flap and the fluoro-substituted ring in an axial position. In the crystal, mol-ecules are linked via N-H⋯S hydrogen bonds, forming chains of R 2 (2)(8) rings along [100]. In one independent mol-ecule, an intra-molecular C-H⋯O hydrogen bond is observed.
