Then, 32.3 g of 1-(2-hydroxy-4-methoxy-3-isopentylphenyl)-3-(4-hydroxyphenyl)-1-propanone was dissolved in 150 ml of anhydrous acetone, 32.6 g of anhydrous potassium carbonate was added to the solution, and the mixture was stirred for 30 minutes. Then, 17.3 g of methyl α-bromoacetate was added to the reaction mixture, and the mixture was stirred at room temperature for 1 day to effect a reaction. After the reaction, the reaction mixture was neutralized with dilute hydrochloric acid and extracted with ethyl acetate, and the solvent was removed from the extract by distillation to obtain 37.0 g (yield=94.6%) of 1-(2-hydroxy-4-methoxy-3-isopentylphenyl)-3-(4-methoxycarbonylmethoxyphenyl)-1-propanone in the form of a colorless prism.
