A mixture of 25 g of (4-tert-butyloxyphenyl)diphenylsulfonium p-toluenesulfonate, 0.5 g of p-toluenesulfonic acid monohydrate, and 75 g of methanol was stirred at 80° C. for 5 hours. The reaction solution was cooled to room temperature and concentrated in vacuum, to which 100 g of methylene chloride and 50 g of deionized water were added. The organic layer was separated, washed with water, and concentrated in vacuum. To the concentrate, 100 g of MIBK was added. This was concentrated in vacuum again, obtaining 24 g of the target compound, (4-hydroxyphenyl)diphenylsulfonium p-toluenesulfonate as oily matter. Yield 96%.
