Synthesis of [1,2,3]Triazolo[4,5-d]pyrimidine 3-Oxides
摘要:
[1,2,3]Triazolo[4,5-d]pyrimidine 3-oxides were synthesized by replacement of the amino group in 6-aminouracil by hydroxyamino, coupling of the resulting 6-hydroxyaminopyrimidine with benzenediazonium salts, and oxidation of 6-hydroxyamino-5-phenylazouracils with a solution of K-3[Fe(CN)(6)] in water.
