title: Ethyl 2-amino-6-benzyl-4,5,6,7-tetra-hydro-thieno[2,3-c]pyridine-3-carboxyl-ate.
abstract: In the title compound, C(17)H(20)N(2)O(2)S, the tetra-hydro-pyridine ring adopts an envelope conformation with the N atom at the flap position; the phenyl ring makes a dihedral angle of 81.06 (10)° with the thio-phene ring. The amino group links with the carbonyl O atom via intra-molecular N-H⋯O hydrogen bonding, forming a six-membered ring. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into infinite chains running along the b axis.
