It is intended to provide a simple and efficient method for producing a nucleic acid base having a perfluoroalkyl group. In the presence of a sulfoxide, a peroxide and an iron compound, by reacting a halogenated perfluoroalkyl and a nucleic acid base (for example, a uracil, a cytosine, an adenine, a guanine, a hypoxanthine, a xanthine or the like), a perfluoroalkyl nucleic acid base useful as a pharmaceutical intermediate is economically produced. |
