3-Aminothieno[2,3-b]pyridine-2-carboxamides react with chloroacetyl chloride to afford 3-(chloroacetylamino)thieno[2,3-b]pyridine-2carboxamides. The latter upon treatment with sodium azide gave 3-(azidoacetylamino)thieno[2,3-b]pyridine-2-carboxamides. The reaction of 3-(chloroacetylamino)thieno[2,3-b]pyridine-2-carboxamides with sulfur and amines afforded new monothiooxamides.
