Procedure

A 100-mL eggplant shaped flask was charged with 1.0 g of sodium 2,4,6-tricyclohexylbenzoate (prepared in Synthesis Example 1-6), 0.9 g of triphenylsulfonium methylsulfate, 10 g of methyl isopropyl ketone, 10 g of 1-pentanol, and 5 g of water, which were stirred at room temperature for 1 hour. The organic layer was separated from the reaction mixture and washed with water. After washing, the organic layer was concentrated by distilling off the solvent. The liquid concentrate was crystallized from 30 g of diisopropyl ether. The crystal precipitate was filtered and dried, obtaining the target compound, triphenylsulfonium 2,4,6-tricyclohexylbenzoate as white crystal. Amount 1.2 g, yield 76%.
