Under cooling with ice, a solution of 5.7 g (50 mmol) of methanesulfonyl chloride in methylene chloride (25 ml) was dropwise added thereto, followed by further stirring for one hour. The reaction liquid was poured into water, followed by the extraction with methylene chloride. After the organic phase was washed with water and dried, it was subjected to vacuum concentration. 13.1 g of the title compound was obtained as a wax (yield 100%).
