Crystal structure of ethyl 4-(2-meth-oxy-phen-yl)-6-methyl-2-sulfanyl-idene-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.
In the title compound, C15H18N2O3S, the hydro-pyrimidine 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 hydro-pyrimidine ring, making a dihedral angle of 85.51 (8)°, and the meth-oxy O atom lies over the centre of the pyrimidine ring. In the crystal, weak N-H⋯S inter-actions form a zigzag chain running along the b-axis direction.
