Procedure

After dissolving 4-(4-amino-3-chlorophenoxy)-6-cyano-7-((1-methyl-3-piperidyl)methoxy)quinoline (246 mg, 0.582 mmol) in dimethylformamide (6 ml) under a nitrogen atmosphere, pyridine (0.19 ml, 2.33 mmol) and phenyl chloroformate (0.15 ml, 1.16 mmol) were added dropwise at room temperature, and the mixture was stirred for 1 hour. Cyclopropylamine (0.20 ml, 2.91 mmol) was added dropwise, and the mixture was further stirred for 3 hours. The reaction solution was distributed between ethyl acetate and saturated aqueous sodium bicarbonate, and the organic layer was washed with water and saturated saline and dried over anhydrous sodium sulfate. The solvent was distilled off, the residue was suspended in methanol and diluted with water, and the crystals were filtered out and dried at 70° C. to obtain the title compound (198.7 mg, 0.393 mmol, 67.5%) as light yellow crystals.
