5-Acetyl-4-(4-methoxy-phen-yl)-6-methyl-3,4-dihydro-pyrimidine-2(1H)-thione

Abstract

In the title mol-ecule, C(14)H(16)N(2)O(2)S, the heterocyclic ring adopts an envelope conformation with the plane through the five coplanar atoms making a dihedral angle of 88.99 (4)° with the benzene ring, which adopts an axial orientation. The thionyl, acetyl and methyl groups all have equatorial orientations. Inter-molecular N-H⋯S, N-H⋯O, C-H⋯O and C-H⋯S hydrogen bonds are found in the crystal structure.
