Crystal structure of ethyl 4-(2-methoxyphenyl)-6-methyl-2- sulfanylidene-1,2,3,4-tetrahydropyrimidine-5-carboxylate

In the title compound, C15H18N2O3S, the hydropyrimidine ring
adopts a sofa conformation with the methine C atom as the
flap. The benzene ring is almost perpendicular to the mean
plane of the hydropyrimidine ring, making a dihedral angle of
85.51 (8), and the methoxy O atom lies over the centre of the
pyrimidine ring. In the crystal, weak N—H  S interactions
form a zigzag chain running along the b-axis direction.
