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)degrees, and the methoxy O atom lies over the centre of the pyrimidine ring. In the crystal, weak N-H center dot center dot center dot S interactions form a zigzag chain running along the b-axis direction.
