title: 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, C(20)H(25)N(3)O(3)S(2), the piperazine ring exhibits a chair conformation and the tetra-hydro-pyridine ring exhibits a half-chair conformation. The folded conformation of the mol-ecule is defined by the N-C-C-N torsion angle of -70.20 (2) °. Inter-molecular C-H⋯S and C-H⋯O hydrogen bonds help to establish the packing.
