biostudies-literature00460Unknown68(Pt 7)Mukhtar AIn the title compound, C(17)H(18)N(2)O(3)S, the dihedral angles between the thio-phene ring and the ethyl ester group and the pyridine-4-carboxamide unit are 7.1 (2) and 9.47 (11)°, respectively. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds between the tetra-hydro-1-benzothio-phene and the pyridine-4-carboxamide residues generate R(2) (2)(16) loops. There exists positional disorder in three methelene groups of the cyclo-hexane ring and the terminal C atom of the ethyl ester side chain in a 0.691 (14):0.309 (14) occupancy ratio.Acta crystallographica.
