Versuchsvorschrift

After dissolving 4-(4-(((4-fluoroanilino)carbonyl)amino) phenoxy)-7-methoxy-6-quinolinecarboxylicacid (84 mg, 0.19 mmol) in dimethylformamide (1 ml), there were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (54 mg, 0.28 mmol), 1-hydroxy-1H-benzotriazolemonohydrate (38 mg, 0.28 mmol), triethylamine (0.079 ml, 0.56 mmol) and 2-methoxyethanol (0.15 ml) while stirring on ice, and the mixture was stirred overnight at room temperature. The reaction solution was directly 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 (47.1 mg, 0.093 mmol, 49.6%) as white crystals.
