Reaction Steps
A solution of 1-{(R)-1-[9-((1R,2S,3R,4S)-4-amino-2,3-dihydroxy-cyclopentyl)-6-(2,2-diphenyl-ethylamino)-9H-purin-2-yl]-pyrrolidin-3-yl}-3-pyridin-3-yl-urea (Example 26 step 2) (17 mg, 26 μmol) in THF (1 ml) is treated with tert-butoxycarbonylamino-acetic acid 2,5-dioxo-pyrrolidin-1-yl ester (9 mg, 29 μmol) and stirred at room temperature overnight. The resulting solution is treated with 1.25 M HCl in EtOH (1 ml) and stirred at room temperature for 2 days. Purification by C-18 reverse phase column chromatography eluting with acetonitrile:water:HCl (0.1%) (gradient of 0 to 100% acetonitrile) yields the title compound. (MH+ 691.99)
