3-Acetyl-1,7-diphenyl[1,2,4]triazolo[4,3-a]pyrimidin-5(1H)-one (1) reacts with N,N-dimethylformamide dimethylacetal (DMFDMA) yielding the enaminone 2. The latter compound reacts with active methylene compounds, hydrazine hydrate, hydroxylamine and some heterocyclic amines to afford trisubstituted pyridine, substituted pyrazole, substituted isoxazole and azolopyrimidines.
