Procedure

0.24 g (1.0 mmol) of cytidine was weighed and placed in a 50 ml two-neck flask equipped with a magnetic rotor and the atmosphere in the flask was replaced with argon. The following materials were added thereinto: 4.0 ml of dimethyl sulfoxide, 1.0 ml of a 3.0 mol/l dimethyl sulfoxide solution of trifluoromethyl iodide, 0.3 ml of a 1.0 mol/l aqueous solution of iron (II) sulfate and 0.2 ml of a 30% hydrogen peroxide aqueous solution. The mixture was stirred at 40 to 50° C. for 20 minutes and then the resulting solution was cooled to room temperature. Formation of 5-trifluoromethylcytidine (19F-NMR yield: 24%) was confirmed by 19F-NMR with 2,2,2-trifluoroethanol as an internal standard. 5-Trifluoromethylcytidine was obtained (0.034 g, yield: 11%) by column chromatography.
