실험 절차

To a solution of 5-(N-trityl-L-valyloxymethyl)-6-stearoyloxyhexanoic acid (462 mg, 0.6 mmole) and 2′,3′-dideoxy-3′-fluoroguanosine (340 mg, 1.25 mmol) in DMF (3 ml) were added dimethylaminopyridine (7 mg, 0.06 mmole), and DCC (136 mg, 0.66 mmol). The reaction was kept at room temperature overnight, and then at 40° C. for two hours. The reaction mixture was filtered through Celite and poured into dichloromethane, and washed with aqueous sodium hydrogen carbonate solution. The product 2′,3′-dideoxy-3′-fluoro-5′-O-[5-(N-trityl-L-valyloxymethyl)-6-stearoyloxyhexanoyl]guanosine was isolated by silica gel column chromatography. (93 mg)
