1-(6-Methyl-4-phenyl-2-sulfanyl-idene-1,2,3,4-tetrahydro-pyrimidin-5-yl)ethanone

Abstract

In the title compound, C(13)H(14)N(2)OS, the heterocyclic ring adopts a flattened boat conformation with the plane through the four coplanar atoms making a dihedral angle of 86.90 (13)° with the phenyl ring, which adopts an axial orientation. The thionyl, acetyl and methyl groups all have equatorial orientations. Inter-molecular N-H⋯O, N-H⋯S and C-H⋯O hydrogen bonds are found in the crystal structure.
