Procedure

A mixed solution of 1-(4-isopropylphenyl)-2-(2,3,5-trimethylphenoxy)propan-1-one obtained in Reference Example 346 (61.3 g, 194 mmol), Amberlyst 15 (61.0 g) and a molecular sieve MS 4A (30 g) in toluene (200 mL) was heated under reflux at 80° C. for 2 hours. The reaction solution was filtered through celite, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate:hexane 1:100) to obtain 54.4 g (yield 96%) of the title compound. Oily matter.
