In the title compound, C 21 H 21 N 3 OS, the three fused rings of the 1-benzothieno[3,2-d]pyrimidine system are almost coplanar. The crystal packing is stabilized bystacking interactions and intermolecular C-HÁ Á ÁO hydrogen bonds.
The title compound, C~15~H~16~N~2~O~2~S, contains a five-membered thiophene ring fused to a benzene ring and a substituted pyrimidinone ring. All three rings in each of the independent molecules of the asymmetric unit lie in approximately the same plane. The crystal structure is stabilized by interm
