Ethyl 3-amino-4H-thieno[2,3-b]pyridine-2-carboxylate

Abstract

The molecule of the title compound, C10H10N2O2S, is essentially planar, except for the ethyl group, which is twisted away from the carboxyl plane by −90.5 (3)°. In the crystal structure, molecules are linked into a zigzag sheet propagating along the b axis by intermolecular N—H...O and N—H...N hydrogen bonds.
