2-Hydrazinoquinoline (5.0 grams) was placed in a 250-milliliter three-necked flask equipped with a mechanical stirrer and a reflux condenser. To this flask was added 100 milliliters of acetic acid. The reaction mixture was refluxed for twelve hours, then allowed to cool; acetic acid was removed by evaporation. The solid which remained consisted of pure 1-methyl-s-triazolo(4,3-a)quinoline. The product was recrystallized from ethanol, m.p., 166°-7°C.
