実験手順

30 mg (0.0705 mmol equivalents) of 2,2-dimethyl-5-[(2-nitro-1H-imidazol-1-yl)methyl]-5-(p-toluenesulfonyloxymethyl)-1,3-dioxane was dissolved in 1.0 mL of acetonitrile, 39.8 mg (0.106 mmol equivalents) of Kryptofix 222 (trade name, Merck), 5.1 mg (0.088 mmol equivalents) of potassium fluoride, and 2.0 mg (0.014 mmol equivalents) of potassium carbonate were added thereto, and the mixture was stirred under reflux by heating for 3 hours. After completion of the reaction, the reaction liquid was cooled to room temperature (25° C.), the solvent was then removed by distillation, and the obtained crude product was purified by silica gel column chromatography (eluent: hexane/ethyl acetate (v/v)=2/1) to give 9.2 mg (0.034 mmol equivalents) of 2,2-dimethyl-5-fluoromethyl-5-[(2-nitro-1H-imidazol-1-yl)methyl]-1,3-dioxane.
