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 15H 15F 3N 2O 2S, 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. © Nayak et al. 2011.
