실험 절차

A solution of 2-{9-[(2R,3R,4R,5R)-3,4-bis{[tert-butyl(dimethyl)silyl]oxy}-5-(methoxymethyl)tetrahydro-2-furanyl]-6-[(2,2-diphenylethyl)amino]-9H-purin-2-yl}acetonitrile (1.9 g, 2.6 mmol) (preparation 17) in ethanol (40 ml) saturated with ammonia gas was treated with Raney Nickel (400 mg), pressurised to 414 kPa (60 psi) with hydrogen in a sealed vessel and stirred at room temperature for 4 days. The mixture was then filtered through Arbocel (trade mark) and the residue washed with ethanol. The solvent was removed under reduced pressure from the filtrate, the residue dissolved in pentane and the solvent again removed under reduced pressure to give the title compound as a powder (1.08 g). MS: 733 (MH+).
