実験手順
A solution of (2R,3R,4R,5R)-4-(acetyloxy)-2-[(acetyloxy) methyl]-5-(6-[(2,2-diphenylethyl)amino]-2-{[(isobutylsulfonyl)amino]methyl}-9H-purin-9-yl)tetrahydro-3-furanyl acetate (188 mg, 0.26 mmol) (Preparation 9) and sodium carbonate (140 mg, 1.32 mmol) in a mixture of water (2 ml) and methanol (10 ml) was stirred at room temperature for 6 hours. The solvent was removed under reduced pressure and the residue partitioned between ethyl acetate and brine. The organic phase was separated and the solvent removed under reduced pressure. The residue was then purified by column chromatography on silica gel eluting with a gradient system of dichloromethane:methanol:0.88 ammonia (95:5:0.5 by volume) gradually changing to dichloromethane:methanol:0.88 ammonia (90:10:1 by volume) to afford the title compound (77 mg).
