Acetic Acid → 2',3'-Dideoxy-3'-fluoro-5'-O-[2-(L-valyloxy) stearoyl]guanosine

Participants

Reaction Steps

To a solution of 2′,3′-dideoxy-3′-fluoro-5′-O-[2-(N-FMOC-L-valyloxy) stearoyl]guanosine (800 mg, 0.89 mmole) in 15 ml DMF was added DBU (1.35 g, 8.9 mmole) and the mixture was stirred for 5 minutes at room temperature. Acetic acid (2 ml) was added and the mixture was evaporated under reduced pressure. Water (20 ml) were added and the mixture was extracted three times with dichloromethane. The organic phase was dried with sodium sulfate and evaporated under reduced pressure. The product was isolated by silica gel column chromatography. Yield: 165 mg
