Reaction Steps

To a solution of tert-butyl 2-cyano-5,7-dihydro-6H-pyrrolo[3,4-d]pyrimidine-6-carboxylate (Intermediate 9, Step D) (71 mg, 0.29 mmol) in toluene was added azidotrimethyltin (596 mg, 2.9 mmol). The resulting mixture was heated at 110° C. overnight. After the solvent was removed under reduced pressure, the residue was purified by reverse-phase silica gel chromatography (gradient 5-50% acetonitrile in water containing 0.1% TFA) to yield tert-butyl 2-(1H-tetrazol-5-yl)-5,7-dihydro-6H-pyrrolo[3,4-d]pyrimidine-6-carboxylate. The product was treated as described for Intermediate 9, Step E, to yield the title compound.
