[1,3]Thiazolo[2′,3′:3,4][1,2,4]triazolo[1,5‐a]pyrimidines – A New Heterocyclic System Accessed via Bromocyclization

A facile access to novel condensed system of [1,3]thiazolo[2′,3′:3,4][1,2,4]triazolo[1,5‐a]pyrimidine is presented. This protocol consists of bromine‐assisted direct electrophilic heterocyclization of 3‐N‐allylamine‐5,6‐dihydro[1,3]thiazolo[2,3‐c][1,2,4]triazole. The bromination took place in acetic acid and gave a good yield of the target product, which was dehydrobrominated by sodium acetate action.
