Reaction Steps

Add dibutyloxostannane (0.071 g; 1.33 equiv; 0.29 mmoles) and azidotrimethylsilane (1.6 mL; 56 equiv; 12.01 mmoles) to a stirred solution of 6-[2-(indan-2-ylamino)-5,7-dihydropyrrolo[3,4-d]pyrimidin-6-yl]-6-oxo-hexanenitrile (0.077 g; 1.0 equiv; 0.213 mmoles) in toluene (6 mL). Heat the resulting solution to 105° C. for 16 hours. Cool the reaction mixture to ambient temperature and concentrate. Dissolve the residue in methanol (5 mL) and load the solution on an SCX column (eluting with methanol to 7N ammonia in methanol) to afford the crude product, which is purified by reverse phase chromatography to give 1-[2-(2,3-dihydro-1H-inden-2-ylamino)-5,7-dihydro-6H-pyrrolo[3,4-d]pyrimidin-6-yl]-5-(1H-tetrazol-5-yl)pentan-1-one (0.0265 g; 31%): MS (m/z): 405(M+1).
