Synthesis and reactions of [1,2,4]triazolo[1,5-a]pyrimidinium-2-aminides
Abstract
[1,2,4]Triazolo[1,5-a]pyrimidinium-2-amides were synthesised by treating an appropriate triazolo[1,5-a]pyrimidinium salt with sodium hydroxide or from the reaction of 4-alkyl-3,5-diamino-1,2,4-triazoles with pentane-2,4-dione or 1,1,3,3-tetramethoxypropane.
