Product 1

HCID 715592735-tert-Butyl-3-(3-chloro-pyridin-4-ylmethyl)-7-(3,3-difluoro-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-difluoropyrrolidin-1-yl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine and 4-(bromomethyl)-3-chloropyridine hydrobromide and isolated as yellow gum. MS(m/e): 408.3 (MH+).
