cyanothioacetamide proceeded regioselectively to form 3-cyano-6-methyl-4-trifluoromethylpyridine-2(1H)-thione from which the corresponding 2-alkylthiopyridines and 3-aminothieno[2,3-b]pyridines were obtained. The crystal and molecular structure of 3-cyano-2-ethylthio-6-methyl-4-trifluoromethylpyridine was established by X-ray diffraction analysis.
