Reaction Steps

In analogy to the procedure described for the synthesis of (R)-1-(5-tert-butyl-3-((1-methyl-1H-tetrazol-5-yl)methyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)pyrrolidin-3-ol (example 113, b) 1-(3-Benzyl-5-tert-butyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)-pyrrolidin-3-ol was hydrogenated and subsequently reacted with 5-(chloromethyl)-1-methyl-1H-tetrazole and isolated as light yellow oil. MS (m/e): 359.3 (MH+).
