Reaction Steps
A suspension of 3,5-dipyrazinyl-1,2,4-triazole (0.5 grams) in 20 ml. of acetic anhydride is heated on a steam bath for 17 hours. The resulting solution is filtered and concentrated to a solid. After recrystallization from benzene-hexane, 250 mg. of 1-acetyl-3,5-dipyrazinyl-1,2,4-triazole is obtained, m.p. 128°-130° C.
