Versuchsvorschrift

1-(3-Hydroxyphenyl)ethanone (1.36 g, 10 mmol) was dissolved in acetone (50 mL) and potassium carbonate (2.76 g, 20 mmol) and 1-methylethyl iodide (1.5 mL, 15 mmol) were added sequentially, and the mixture was stirred at 70° C. overnight. The reaction solution was filtered, washed with acetone and concentrated in vacuo. The obtained residue was added water and ethyl acetate, and extracted with ethyl acetate. The organic layer was washed with 1N aqueous solution of sodium hydroxide and brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. 1-(3-(1-methylethoxy)-phenyl)ethanone (1.67 g (yield 94%)) was obtained as a yellow oil.
