Procedure
To a solution of 4-cyanopyridine (4.1 grams, 0.04 mole) in methanol (60 ml.) is added sodium (0.2 grams). The resulting solution is allowed to stand at room temperature for 1/2 hour and is then added to a solution of N-methylisonicotinic acid hydrazide (6 grams, 0.04 mole) in methanol (80 ml.). The solution is refluxed for 3 hours and is then concentrated until a solid separates out of solution. The solid is collected by filtration and, upon recrystallization from ethanol, 1-methyl-3,5-di(4-pyridyl)-1,2,4-triazole is obtained, m.p. 168°-170°C.
