Yield:-

Reaction Conditions:

with acetic anhydride in pyridine;water

Steps:

a (a)
(a) From 5'-deoxy-5-fluorocytidine 5'-Deoxy-5-fluorocytidine (50 mg) was dissolved in dry pyridine (1.3 ml). To the solution was added acetic anhydride (39 ml) with stirring at 0° C. The reaction mixture was stirred for 3 hours at 0° C. After removal of the solvent under reduced pressure, the residue was partitioned between ethyl acetate and ice cooled water. The ethyl acetate layer was dried over magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (dichloromethane/methanol=9/1 as an eluent) followed by recrystallization from isopropanol to give 37 mg of 2',3'-di-O-acetyl-5'-deoxy-5-fluorocytidine: 191.5°-193° C., FAB-MS m/z 330 (MH⁺).
