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.
Indeno[ 1, furan-2,4(3H)-dione derivative pentachloride gave an indanone 5, instead of the expected dihydrofuran 6. The mechanism for the formation of the indanone 5 implies the intermediate acid chloride 7. The formation of 5 instead of 6 is due to facilitation of electrophilic attack of the chlor
In the title compound, C 19 H 20 N 2 O 2 S, the central thienopyrimidine ring system is essentially planar. The molecular structure is stabilized by C-HÁ Á ÁO hydrogen bonds. In the crystal packing, the molecules are linked only by van der Waals forces.
