실험 절차

1,3-Dimethoxybenzene (13.8 grams, 0.1 mole) and p-anisoyl chloride (17 grams, 0.1 mole) were dissolved in 200 milliliters of methylene chloride and stirred at room temperature. Anhydrous aluminum chloride (15 grams) 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 milliliters 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 milliliter portions of pentane, and dried, yielding 2,4,4'-trimethoxybenzophenone.
