In reaction of alkyl 2-amino-5,6-dialkyl-3-cyanopyridine-4-carboxylates with isocyanates formed unstable ureas, and with nitrous acid at 60-70°C alkyl 5,6-dialkyl-2-oxo-1,2-dihydro-4-pyidinecarboxylates were obtained. It was shown for the latter that their reactions with organic acids and amides occurred at the cyano group, and the alkaline hydrolysis involved the ester group.

Previously unknown derivatives of pyridine have been synthesized by reaction of tetracyanoethylated ketones with concentrated aqueous solution of hydrochloric and hydrobromic acids.The unique course of the reaction of 4,4,5,5-tetracyano-2-pentanone with gaseous hydrogen chloride has been demonstrated.
