Procedure

4-Chloro-6,7-dimethoxyquinoline (103 mg) and commercially available 4-methoxyphenol (286 mg) were mixed and stirred at 150° C. for 6 hours. The reaction mixture was neutralized with saturated aqueous sodium hydrogen carbonate and then partitioned between water and ethyl acetate, and the ethyl acetate layer was washed with brine and dried with anhydrous sodium sulfate. After removing the solvent by reduced-pressure distillation, the resulting residue was purified by column chromatography on silica gel eluting first with hexane/ethyl acetate and then with chloroform/ethyl acetate to obtain 2.21 g of the title compound (yield: 88%).
