实验步骤: To a stirred solution of 1-{2-[(cyclopropylmethyl)oxy]-6-hydroxyphenyl}ethanone (56.3 g, 272 mmol) in acetone (1000 mL) was added potassium carbonate (188 g, 1364 mmol), 4-methoxybenzyl chloride (40.9 mL, 300 mmol) and tetrabutyl-ammonium iodide (20.2 g, 54.6 mmol). The mixture was stirred at reflux overnight. The reaction mixture was allowed to cool to room temperature, filtered on Celite®, and then the filtrate was concentrated under reduced pressure. The residue was diluted with water and extracted with ethyl acetate. The separated organic phase was washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure. Then the resulting white solid was recrystallized from ethanol, collected by filtration, washed with ethanol, and dried under reduced pressure to give 1-{2-(cyclopropylmethoxy)-6-[(4-methoxybenzyl)oxy]phenyl}ethanone as a white solid (79.2 g, yield; 89%). at reflux overnight filtered on Celite® the filtrate was concentrated under reduced pressure The residue was diluted with water extracted with ethyl acetate The separated organic phase was washed with brine dried over MgSO4 filtered concentrated under reduced pressure Then the resulting white solid was recrystallized from ethanol collected by filtration washed with ethanol dried under reduced pressure
