Procedure

Employing the same general procedure as for the preparation 5-bromo-2-methoxy-4'-methylbenzophenone (Compound H), 780 mg (3.9 mmol) of 4-bromo-1-methoxy-3-methylbenzene (Compound E) was converted into the title compound using 260 mg (1.9 mmol) of aluminum chloride, 0.6 mL (0.7 g, 4.7 mmol) of p-toluoyl chloride and 17 mL of dichloromethane. Purification by flash chromatography (silica, 5% ethyl acetate in hexane) gave the title compound as a white solid.
