실험 절차

To a solution of 2′,3′-dideoxy-3′-fluoroguanosine (113 mg, 0.42 mmol) and 3-(N-benzyloxycarbonyl-L-valyloxymethyl)-4-stearoyloxy-butyric acid (140 mg, 0.21 mmol) in DMF (2 ml) were added dimethylaminopyridine (3 mg, 0.02 mmol) and DCC (52 mg, 0.25 mmol). After two days, dichloromethane (10 ml) and a few drops of acetic acid were added and the organic phase was filtered through Celite. The filtrate was washed with aqueous sodium hydrogen carbonate solution and the product 2′,3′-dideoxy-3′-fluoro-5′-O-[3-(N-benzyloxycarbonyl-L-valyloxymethyl)-4-stearoyloxy-butanoyl]guanosine was isolated by silica gel column chromatography to yield 51 mg.
