HCID 866833475-tert-Butyl-3-(4-methyl-furazan-3-ylmethyl)-7-(3,3,4,4-tetrafluoro-pyrrolidin-1-yl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine

Procedure

In analogy to the procedure described for the synthesis of 5-tert-butyl-7-(3,3-difluoropyrrolidin-1-yl)-3-ethyl-3H-[1,2,3]triazolo[4,5-d]pyrimidine (example 61), the title compound was prepared from 5-tert-Butyl-7-(3,3,4,4-tetrafluoro-pyrrolidin-1-yl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine and 3-(bromomethyl)-4-methyl-1,2,5-oxadiazole and isolated as light-yellow gum. MS (m/e): 415.3 (MH+).
