Procedure

4-Bromo-3-hydroxy-2-methyl-quinoline (35 mg), 4-chloro-6,7-dimethoxyquinoline (110 mg), and 4-dimethylaminopyridine (89 mg) were suspended in o-dichlorobenzene (5 ml), and the suspension was stirred at 140° C. for 5 hr. The reaction solution was cooled to room temperature, and the solvent was removed by distillation under the reduced pressure. The residue was purified by thin layer chromatography using acetone-chloroform to give the title compound (20 mg, yield 32%).
