Procedure
4-(4-((Cyclopropylamino)carbonyl)amino-3-methylphenoxy)-7-methoxy-6-quinolinecarboxylic acid (30 mg, 0.0736 mmol) and methoxyamine hydrochloride (0.0123 ml) were used for reaction in the same manner as Example 458, and after purification by NH silica gel column chromatography (ethyl acetate:methanol=10:1), the obtained crystals were suspended in ethanol, diluted with hexane, filtered out, washed with hexane and dried by aspiration to obtain the title compound (7 mg, 0.0160 mmol, 21.74%) as light yellow crystals.
