6.1 mg (0.02 mmol) sodium 2-iodobenzenesulfonate prepared by Preparation Example 4, 0.49 g (0.8 mmol) of powdered Oxone (registered trademark), 0.5 g (3.5 mmol) of anhydrous sodium sulfate and 232 mg (1 mmol) of 6-(tert-butyldimethylsilyloxy)hexan-2-ol were added to 5 ml of ethyl acetate, and the mixture was heated at 70° C. while being stirred under a nitrogen for seven hours. The later treatment was carried out in the same way as in Example 1, and then 6-(tert-butyldimethylsilyloxy)hexan-2-one was obtained. The yield of the obtained 6-(tert-butyldimethylsilyloxy)hexan-2-one was determined and the result is shown in Table 2. (Yield 90%)
