Reaction Steps
To 4-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-nicotinoyl-hydrazine (3 g.) in methanol (30 ml.). The reaction mixture is heated 5 hours at reflux and is concentrated to an oil which solidifies. After chromatography on silica gel and recrystallization from acetonitrile 0.8 g. of 1-methyl-3-(3-pyridyl)-5-(4-pyridyl)-1,2,4-triazole melting 132°-133° C is obtained.
