✦ Synopsis

In the title compound, C 17 H 17 N 3 OS 2 , the fused thiophene and pyrimidine rings are almost coplanar. The amino group is involved in both intramolecular and intermolecular hydrogen bonds, the latter linking the molecules into a centrosymmetric dimer.

In the title compound C~20~H~21~Cl~2~N~2~O~2~S, the thienopyrimidine ring system is essentially planar. The crystal packing is stabilized by van der Waals forces and by an intermolecular C—H...O hydrogen-bonding interaction, which links the molecules into zigzag chains.
