실험 절차

0.15 g (1.0 mmol) of N4-acetylcytosine 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: 17 ml of dimethyl sulfoxide, 2.0 ml of a 1N dimethyl sulfoxide solution of sulfuric acid, 1.0 ml of a 3.0 mol/l dimethyl sulfoxide solution of trifluoromethyl iodide, 0.2 ml of a 30% hydrogen peroxide aqueous solution and 0.3 ml of a 1.0 mol/l aqueous solution of iron (II) sulfate. The mixture was stirred at 40 to 50° C. for 20 minutes and then the resulting solution was cooled to room temperature. Formation of N4-acetyl-5-trifluoromethylcytosine (19F-NMR yield: 35%) was confirmed by 19F-NMR with 2,2,2-trifluoroethanol as an internal standard. N4-acetyl-5-trifluoromethylcytosine was obtained as a white solid (0.067 g, yield: 30%) by column chromatography.
