2-[4-(4-Methylphenylsulfonyl)piperazin-1-yl]-1-(4,5,6,7-tetrahydrothieno[3,2-c]pyridin-5-yl)ethanone

Abstract

In the title thienopyridine derivative, C20H25N3O3S2, the piperazine ring exhibits a chair conformation and the tetrahydropyridine ring exhibits a half-chair conformation. The folded conformation of the molecule is defined by the N—C—C—N torsion angle of −70.20 (2) °. Intermolecular C—H...S and C—H...O hydrogen bonds help to establish the packing.
