Procedure

A solution of 139 mg (0.5 mmol) of 2'-deoxy-2'-methylidene-4-N-benzoylcytidine in 10 ml of methanolic ammonia was stirred at room temperature for 6 hours to cause reaction and the solvent distilled off under reduced pressure. The residue was developed through a silica gel column (1.6×10 cm, 20% ethanol-chloroform being used as a solvent for elution), fractions containing the desired compound collected, 2 ml of 1N hydrochloric acid added, and the solvent distilled off under reduced pressure. The residue was crystallized from acetone-methanol to obtain 115 mg (yield 83%) of 2'-deoxy-2'-methylidenecytidine.
