The title product was prepared as described in U.S. Pat. No. 4,230,862. To 30 ml of dioxane were added 3-phenyl-4-(4-methoxybenzoyl)-1,2-dihydronaphthalene (1.90 g, 5.58 mmol), prepared as described in Example 3, supra, and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (2.00 g, 8.81 mmol). The resulting mixture was heated to reflux and refluxed for twelve hours under a nitrogen atmosphere. The mixture was then cooled and evaporated to dryness. The residue was partitioned between ether and water. The organic fraction was washed 5N sodium hydroxide (5×20 ml), followed by a wash with brine. The mixture was then dried over magnesium sulfate and evaporated to give 1.9 grams of substantially pure 1-(4-methoxybenzoyl)-2-phenylnaphthalene.
