A mixture of 68.1 g (0.5 mole) of 4'-hydroxyacetophenone, 100.3 g (0.5 mole) of 3-phenylpropyl bromide, 69.0 g (0.5 mole) of potassium carbonate and 500 ml of anhydrous acetone is refluxed with stirring for 8 hours. After adding 1 liter of water the product is extracted into ether, the extract is washed with water and 2 N sodium carbonate solution and dried over anhydrous sodium sulfate and the solvent is evaporated. The resulting oil (125.8 g) begins to crystallize and yields after two recrystallizations from ether-hexane and ether, respectively, 73.9 g (58% yield) of the desired product, M.P. 80°-81°.
