Pyridine-2-carbonitrile → HCID 21853020, compound

Participants

Reaction Steps

To 2-cyanopyridine (2 g.) in methanol (30 ml.) is added sodium (0.1 g.). The solution is allowed to stand 0.5 hours at ambient temperature and is then added to a solution of 1-methyl-2-isonicotinoylhydrazine (3 g.) in methanol (50 ml.). The solution is heated at reflux 4 hours and concentrated to a gum. After chromatography on silica gel and recrystallization from acetonitrile-water 450 mg. of 1-methyl-3-(4-pyridyl)-5-(2-pyridyl)-1,2,4-triazole are obtained, melting at 145°-146° C.
