실험 절차

In analogy to the procedure described for the synthesis of 5-tert-butyl-7-(3,3-difluoro-pyrrolidin-1-yl)-2-ethyl-2H-[1,2,3]triazolo[4,5-d]pyrimidine (example 3, step b), the title compound was prepared from Trifluoro-acetic acid (S)-1-(5-tert-butyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)-pyrrolidin-3-yl-ester and 3-(bromomethyl)-4-methyl-1,2,5-oxadiazole. After completion of the substitution reaction methanol was added and the mixture was stirred for 1 h at room temperature and subsequently subjected to purification with preparative HPLC on reversed phase eluting with a gradient formed from acetonitrile, water and NEt3. After evaporation of the product containing fractions the title compound was isolated as light-yellow gum. MS (m/e): 359.3 (MH+).
