title: Ethyl 6-methyl-2-sulfanyl-idene-4-[4-(trifluoro-meth-yl)phen-yl]-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.
abstract: The title compound, C(15)H(15)F(3)N(2)O(2)S, adopts a conformation with an intra-molecular C-H⋯π inter-action. The dihedral angles between the planes of the 4-(trifluoro-meth-yl)phenyl and ester groups with the plane of the six-membered tetra-hydro-pyrimidine ring are 81.8 (1) and 16.0 (1)°, respectively. In the crystal structure, inter-molecular N-H⋯S hydrogen bonds link pairs of mol-ecules into dimers and N-H⋯O inter-actions generate hydrogen-bonded mol-ecular chains along the crystallographic a axis.
