Synthesis of Novel N,3-Substituted 3H-[1,2,3]Triazolo[4,5-d]pyrimidin-5-amines

Abstract

Novel N,3-substituted 3H-[1,2,3]triazolo[4,5-d]pyrimidin-5-amines were prepared by an expedient method starting from 2-chloro-5-nitropyrimidin-4-yl thiocyanate via N^²,N⁴-substituted 5-nitropyrimidine-2,4-diamines.

Key words

triazolopyrimidines - 5-nitropyrimidine-2,4-diamines - cyclization - hydrogenation - nucleophilic aromatic substitution
