Abstract
The chlorine atom in 2-chloro-3-cyanopyridines is readily replaced by primary and secondary aliphatic amines and heterocyclic amines to give 2-aminopyridines. 2-Chloro-3-cyanopyridines react with hydrazine hydrate and sodium azide to give hydrazinopyridines, pyridopyrazoles, azidopyridines, and pyridotetrazoles.
2-chloro-3-cyanopyridines can be easily substituted with aliphatic amines and heterocyclic amines to produce 2-aminopyridines, and they react with hydrazine hydrate and sodium azide to produce hydrazinopyridines, pyri
