실험 절차

After dissolving 4-amino-3-chlorophenol (2.22 g, 15.45 mmol) in dimethylsulfoxide (40 ml), sodium hydride (618 mg, 15.45 mmol) was gradually added at room temperature and the mixture was stirred for 30 minutes. Methyl 7-(benzyloxy)-4-chloro-6-quinolinecarboxylate (4.05 g, 12.36 mmol) was added, and the mixture was heated at 100° C. for 2 hours while stirring. Upon cooling to room temperature, the reaction solution was distributed between ethyl acetate and water, and the organic layer was washed with water and saturated brine and dried over anhydrous sodium sulfate. The solvent was distilled off and subjected to silica gel column chromatography (eluent-ethyl acetate), the fraction containing the target substance was concentrated, suspended in ethyl acetate and diluted with hexane, and the crystals were filtered out and blow-dried to obtain the title compound (3.938 g, 9.06 mmol, 73.3%) as light brown crystals.
