Versuchsvorschrift

To a solution of ((1S,2R,3S,4R)-4-{6-(2,2-diphenyl-ethylamino)-2-[(R)-3-(3-pyridin-3-yl-ureido)-pyrrolidin-1-yl]-purin-9-yl}-2,3-dihydroxy-cyclopentyl)-carbamic acid benzyl ester trifluoroacetate (step 1) (35 mg, 46 μmol) in ethanol (1 ml) under an inert atmosphere of argon is added 10% palladium on carbon (10 mg). The reaction mixture is purged with argon and placed under a positive atmosphere of hydrogen overnight after which time, the mixture is filtered through celite and the catalyst washed with ethanol. The organic portions are combined and concentrated in vacuo to yield the title compound. MS (ES+) m/e 635 (MH+).
