In the title compound, C 23 H 19 ClN 2 O 3 S, the central pyrimidine ring is significantly puckered, assuming an intermediate conformation between an envelope and a screw-boat form. Short intermolecular C-HÁ Á ÁO, C-HÁ Á Á andstacking interactions contribute to the stability of the crystal packing.
