Ethyl 8-amino-7-(furan-2-yl)-5,6-dihydrothieno[2,3-b]benzo[h]quinoline-9-carboxylate

Abstract

In the title compound, C22H18N2O3S, the two independent molecules in the asymmetric unit form a dimerviaN—H...O hydrogen bonds. In the crystal, the molecular layers can be found in the (110) plane, connected by C—H...π interactions. Atoms of the furan ring of one independent molecule are disordered over two sets of sites with an occupancy ratio 0.735 (3):0.265 (3).
