Ethyl 2-acetamido-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate

Abstract

In the title compound, C13H17NO3S, the dihedral angles between the thiophene ring and the ethyl ester and acetamide groups are 5.21 (13) and 10.06 (16)°, respectively. The cyclohezene ring adopts a half-chair conformation. An S(6) ring is formed due to an intramolecular N—H...O hydrogen bond. In the crystal, molecules are linked by C—H...O interactions between the tetrahydro-1-benzothiophene unit and the ethyl ester group, forming C(7) chains propagating along the b-axis direction.
