実験手順

(3-Hydroxy-quinolin-2-yl)-ethanone (878 mg), 7-benzyloxy-4-chloro-6-methoxyquinoline (7.03 g), and 4-dimethylaminopyridine (3.44 g) were suspended in o-dichlorobenzene (20 ml), and the mixture was stirred at 130° C. overnight. The reaction solution was cooled to room temperature, water was then added thereto, and the mixture was extracted with chloroform. The chloroform layer was washed with saturated brine and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography using chloroform-acetone to give 1-[3-(7-benzyloxy-6-methoxy-quinolin-4-yloxy)-quinolin-2-yl]-ethanone (758 mg, yield 36%).
