A solution of benzyl 4-[({[(2-{[(6-[(2,2-diphenylethyl)amino]-9-{(2R,3R,4S,5S)-5-[(ethylamino)carbonyl]-3,4-dihydroxytetrahydro-2-furanyl}-9H-purine-2-yl)carbonyl]amino}ethyl)amino]carbonyl}amino)methyl]benzoate (Preparation 55) (150 mg, 0.18 mmol) in ethanol (10 ml) was hydrogenated at room temperature over 10% w/w palladium-on-carbon (30 mg) for 28 hours at 414 KPa. The catalyst was removed by filtration through Arbocel (trade mark) and solvent evaporated under reduced pressure to afford the title compound as a white powder (26 mg).
