Reaction Steps

To a solution of 4-(S)-(2-amino-6-phenoxy-4H-pyrido[3,4-d]pyrimidin-3-yl)-5-methyl-hexanoic acid (4-cyano-cyclohexyl)-methyl-amide (0.26 g, 0.43 mmol) and trimethylsilylazide (0.17 mL, 1.29 mmol) in DME (1.5 mL) was added dibutyltin oxide (0.10 g, 0.40 mmol). The mixture was then heated in a microwave at 150° C. for 20 min. The solution was purified by HPLC to yield 4-(S)-(2-amino-6-phenoxy-4H-pyrido[3,4-d]pyrimidin-3-yl)-5-methyl-hexanoic acid methyl-[4-(1H-tetrazol-5-yl)-cyclohexyl]-amide as a white solid, as its corresponding trifluoroacetate salt.
