Into a flask, 30 g of 4-hydroxyphenyldiphenylsulfonium perfluorobutanesulfonate and 300 g of dichloromethane were added to prepare a solution. In the flask, a nitrogen gas was blown. To the solution, 17.9 g of N,N-diethylcarbamoyl chloride was added and then 10.5 g of triethylamine was added thereto. The resultant mixture was stirred at room temperature for 1 hour. To the obtained reaction mixture, 100 g of ion-exchanged water was added and an organic layer was obtained by separation. The obtained organic layer was washed with 300 mL of distillated water and then dried over anhydrous magnesium sulfate. Magnesium sulfate was removed by filtration and the obtained filtrate was concentrated. The obtained residue was dried under reduced pressure to obtain 26.7 g of 4-(N,N-diethylaminocarboxy)phenyldiphenylsulfonium perfluorobutanesulfonate.
