Procedure

After dissolving tert-butyl 4-(((4-(4-amino-3-chlorophenoxy)-6-cyano-7-quinolyl)oxy)ethyl)-1-piperidine carboxylate (486.5 mg, 0.930 mmol) in dimethylformamide (5 ml) under a nitrogen atmosphere, pyridine (0.170 ml, 2.09 mmol) and phenyl chloroformate (0.175 ml, 1.34 mmol) were added dropwise at room temperature, and the mixture was stirred for 1 hour. Cyclopropylamine (0.322 ml, 4.65 mmol) was added dropwise, and the mixture was further stirred overnight. 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 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 (343 mg, 0.566 mmol, 60.8%) as light yellow crystals.
