5-(2-Cyano-benz-yl)-4,5,6,7-tetra-hydro-thieno[3,2-c]pyridin-2-yl acetate.

In the title mol-ecule, C17H16N2O2S, the tetra-hydro-pyridine ring exhibits a half-chair conformation. The mean planes of the ester chain and benzene ring are twisted by 5.5†(1) and 81.32†(5)°, respectively, from the plane of thio-phene ring. In the crystal, weak C-H⋯O inter-actions link mol-ecules related by translation along [100] into chains.
