Procedure

A mixed solution of the mixture of 1-(2-isopropyl-6-methoxyphenyl)-2-(2,3,5-trimethylphenoxy)ethanone and 1-(4-isopropyl-2-methoxyphenyl)-2-(2,3,5-trimethylphenoxy)ethanone obtained in Reference Example 171 (6.27 g, 19.2 mmol) and Montmorillonite KSF (9.40 g) in toluene (100 mL) was stirred under argon atmosphere at 90° C. for 5 hours. The reaction solution was filtered through celite, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate:hexane=15:85) to obtain 2.34 g (yield 40%) of the title compound. Oily matter.
