Procedure

To a solution of 2-(2,3-dimethylphenoxy)-2-methyl-1-(4-methylphenyl)propane-1-ol synthesized in Reference Example 135 (17.0 g, 60 mmol) in toluene (200 mL) was added trifluoromethanesulfonate (0.53 mL, 6 mmol) at 0° C., and the mixture was warmed to 50° C. The mixture was stirred at the same temperature for 30 minutes and was reacted under reflux condition for 2 hours. The reaction solution was cooled to 0° C., and then was poured into a saturated sodium hydrogen carbonate solution. The organic layer was separated, washed with a saturated brine, and dried over sodium sulfate, and the solvent then was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:9) to obtain 9.3 g (yield 58%) of the title compound as an oily matter.
