実験手順

5 mg (11.4 μmol equivalents) of 2,2-dimethyl-5-[2-(2-nitro-1H-imidazol-1-yl)ethyl]-5-(p-toluenesulfonyloxymethyl)-1,3-dioxane was dissolved in 1 mL of acetonitrile, 14 mg (34.5 μmol equivalents) of Kryptofix 222 (trade name, Merck), 0.82 g (14.1 μmol equivalents) of potassium fluoride, and 0.4 mg (2.9 μmol equivalents) of potassium carbonate were added thereto, and the mixture was refluxed while heating for 5 hours. After completion of the reaction, water was added and the mixture was extracted three times with chloroform. The combined chloroform layers were dried with anhydrous magnesium sulfate and subsequently concentrated under vacuum. The obtained crude product was purified by silica gel column chromatography to give a trace amount of 2,2-dimethyl-5-fluoromethyl-5-[2-(2-nitro-1H-imidazol-1-yl)ethyl]-1,3-dioxane.
