چکیده
In the title mol-ecule, C13H14N2O3S, the di-hydro-pyrimidine ring is in a flattened sofa conformation, with the methine C atom forming the flap. The dihedral angle between the mean plane of the five essentially planar atoms of the di-hydro-pyrimidine ring [maximum deviation = 0.056 (4) Å] and the benzene ring is 89.4 (2)°. The O atom of the carbonyl group is in a trans conformation with respect to the C=C bond of the di-hydro-pyrimidine ring. In the crystal, N-H⋯O and O-H⋯S hydrogen bonds connect mol-ecules, forming a two-dimensional network parallel to (001).
