The 4-phenylmethylbenzenesulfonic acid crude product obtained in Synthesis Example 1 was added to the aqueous triphenylsulfonium chloride solution obtained in Synthesis Example 2 and 90 g of dichloromethane, which was stirred for one hour at room temperature. The organic layer was separated, washed with 100 g of water, and evaporated in vacuum. The residue, 27 g, was purified by silica gel column chromatography (eluent, dichloromethane/methanol), obtaining the end product, triphenylsulfonium 4-phenylmethylbenzenesulfonate. It was 21 g (yield 52%) of an oily matter containing a minor amount of solvents (methanol, etc.).
