A solution of 15.28 g (59.6 mmol) of 1,3-dimethoxy-2-(3-phenylpropyl)benzene from the preceding example, and 4.68 g (59.6 mmol) of acetyl chloride, in 306 mL of dichloromethane was stirred at -5° to 0° C. and 7.95 g (59.6 mmol) of aluminum chloride was added. The resulting mixture was stirred at -5° to 0° C. for 2 hr and then allowed to warm to room temperature before being poured onto ice. Work-up with ether in the usual manner gave a product which was chromatographed on silica gel. Elution with 7:3 hexane-ether afforded 10.0 g (56.3%) of the title compound as a pale-yellow oil.
