5-(Chloromethyl)-3-methyl-1,2,4-oxadiazole → (S)-1-[5-tert-Butyl-2-(3-methyl-[1,2,4]oxadiazol-5-ylmethyl)-2H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl]-pyrrolidin-3-ol

Participants

Reaction Steps

In analogy to the procedure described for the synthesis of (S)-1-[5-tert-Butyl-2-(4-methyl-furazan-3-ylmethyl)-2H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl]-pyrrolidin-3-ol (example 73), 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 5-(chloromethyl)-3-methyl-1,2,4-oxadiazole and isolated as brown gum. MS (m/e): 359.3 (MH+).
