実験手順

After dissolving 4-(3-chloro-4-(((methylamino) carbonyl)amino)phenoxy)-7-methoxy-6-quinolinecarboxylic acid (100 mg, 0.250 mmol) in dimethylformamide (3 ml), there were added a 40% methylamine-methanol solution (0.100 ml), triethylamine (0.250 ml) and 1H-1,2,3-benzotriazol-1-yloxy) (tri(dimethylamino))phosphonium hexafluorophosphate (221mg, 0.500 mmol) in that order at room temperature, and the mixture was stirred for 15 hours. 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 magnesium sulfate. The solvent was distilled off, the residue was suspended in ethyl acetate and diluted with hexane, and the crystals were filtered out and blow-dried to obtain the title compound (85.0 mg, 0.204 mmol, 82%) as white crystals.
