実験手順

Further, by using 2-methoxy-3,5-dimethylphenol (7.60 g, 41.7 mmol), synthesis was also performed according to the following method. That is, to a solution of n-heptane (76 mL) containing 2-methoxy-3,5-dimethylphenol (7.60 g, 41.7 mmol) and isobutyl aldehyde (5.71 mL, 62.6 mmol), trifluoromethanesulfonic acid (1.85 mL, 20.9 mmol) was added dropwise, and the mixture was stirred at 55° C. for 2.5 hours. After cooled to room temperature, the reaction solution was washed with water and dried using anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The obtained residue was purified by basic silica gel chromatography (hexane-ethyl acetate 100:0) and silica gel chromatography (hexane-ethyl acetate 100:0-95:5) to give 8.70 g of the title compound (yield 100%).
