Procedure

1 mL of a 7 mol/L ammonia/methanol solution was added to a solution of 9.6 mg of 1-(2-deoxy-3,5-bis-O-benzoyl-4-thio-β-D-ribofuranosyl)cytosine in 1 mL of methanol, and the obtained mixture was then stirred at room temperature for 3 hours. Thereafter, the solvent was distilled away under reduced pressure, and the obtained residue was then purified by silica gel column chromatography (ethyl acetate/methanol=95/5 to 30/70), so as to obtain 4.7 mg of 1-(2-deoxy-4-thio-β-D-ribofuranosyl)cytosine in the form of a white solid.
