Ethyl 3-acetyl-4-(3-meth-oxy-phen-yl)-6-methyl-2-sulfanyl-idene-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.

ABSTRACT: In the title compound, C(17)H(20)N(2)O(4)S, the aryl ring is positioned perpendicular to the dihydro-pyrimidine ring, the dihedral angle between the ring planes being 77.48?(9)°. The carboxyl-ate and methyl groups are in a cis conformation with respect to the C=C bond. The dihydro-pyrimidine ring adopts a twist-boat conformation. The crystal structure is stabilized by N-H?O and C-H?O inter-actions, the former resulting in mol-ecular chains along the b axis and the latter forming inversion dimers.
