Acetic Acid → 6-(Phenyl)-1,2,4-triazolo[1,5-a]pyrimidine

Participants

Reaction Steps

An equimolar mixture of (phenyl)formimidoylacetaldehyde and 3-amino-1,2,4-triazole in glacial acetic acid (5 ml. acetic acid to 0.01 mole of reagents) is refluxed for 2 hours and allowed to cool to room temperature. The solid which separates is collected, washed with glacial acetic acid and dried. The solid is recrystallized from glacial acetic acid to give the product, m.p. 164°-167° C.
