Reaction Steps
To a solution of 2′,3′-dideoxy-3′-fluoroguanosine (269 mg, 1.0 mmole in absolute DMF were added pyridine (198 mg, 2.5 mmole) and a solution of 3-(N-CBZ-L-valyloxymethyl)-4-stearoyloxy-butoxycarbonyl chloride (750 mg, 1.1 mmole) in 5 ml dichloromethane. The mixture was stirred for three days at room temperature. The solution was evaporated under reduced pressure and the product was isolated by silica gel column chromatography. Yield: 120 mg
