The synthesis and reactivity of the 1,2,3-triazolo[3,4-α]pyrimidine ring system. A new route to 2-substituted pyrimidines
Abstract
Derivatives of the 1,2,3-triazolo[3,4-α]pyrimidine ring system are formed by condensing 5-amino-1H-1,2,3-triazoles with acetylacetone or ethyl acetoacetate in the presence of piperdine.
