Procedimiento

Triethylamine was dissolved in cold water, and hydrochloric acid was added thereto to adjust the pH of the reaction liquid to fall within a range of 1 to 3. Then sodium 1,1,3,3,3-pentafluoro-2-(benzoyloxy)propanesulfonate and dichloromethane were added thereto and stirred. The separated organic layer was washed with water, and dichloromethane was removed under reduced pressure from the washed organic layer. To the residue thus obtained, diethyl ether was added for recrystallization. The resultant was filtrated and dried to obtain a desired product at a yield of 75%.
