Procedure

When 9.5 g (0.025 moles) of bis(perfluoroethylsulfonyl)imide was added to the aforementioned aqueous solution of 2-oxo-2-phenylethylthiacyclopentaniumbromide, oily matter was separated therefrom. This oily matter was extracted by 1000 g of dichloromethane. An organic layer was washed with 50 g of water four times, and the organic layer was concentrated by a rotary evaporator, thus obtaining 15 g of oily substance. The 50 g of diethyl ether was added to this oily substance for crystallization. Resultant crystals were subjected to filtration under vacuum, and drying. As a result, 13 g of white crystals was obtained. The yield was 66%.
