Ethyl 3-(4-methyl-benzene-sulfonamido)thieno[2,3-b]pyridine-2-carboxyl-ate.

ABSTRACT: The thieno[2,3-b]pyridine ring system of the title compound, C(17)H(16)N(2)O(4)S(2), is essentially planar, the amino and carbonyl groups being nearly coplanar with the heterocyclic ring system. There are two N-H⋯O hydrogen-bonding inter-actions involving the same N-H donor set and two different acceptors, one in an intra-molecular bond helping to fix the mol-ecular geometry and the other defining a dimeric structure around the symmetry centre at (0, , ).
