실험 절차

1,3-Dimethoxybenzene (13.8 g) and p-anisoyl chloride (17 g) were dissolved in a reaction flask containing 200 mL of methylene chloride and stirred at room temperature. Anhydrous aluminum chloride (15 g) was added slowly to the reaction mixture over a period of 15 minutes with stirring. After stirring an additional 15 minutes, the contents of the flask were carefully poured into 200 mL of a mixture of ice and dilute hydrochloric acid. The organic fraction was separated and washed with water. The solvent was removed on a rotary evaporator leaving an oily product that solidified on standing. This solid was broken-up, washed with two 50 mL ortions of pentane, and dried, yielding (2,4-dimethoxy-phenyl)-(4-methoxy-phenyl)-methanone.
