A novel method has been developed for the synthesis of 8-alkyl[1,2,4]triazolo[5,1-b]purines from 6‑nitro[1,2,4]triazolo[1,5-a]pyrimidin-7-ones via successive phosphoryl chloride-mediated chloro-desoxygenation, aminodehalogenation, and reduction to give 7-alkylamino-6-amino[1,2,4]triazolo-[1,5‑a]pyrimidines. The latter can be cyclized in the presence of formic acid.
