Procedure

The 4-(4-aminophenoxy)-6-cyano-7-methoxyquinoline (747 mg) obtained in Production Example 14 was dissolved in 7 ml of dimethylformamide and 0.34 ml of pyridine, and the solution was cooled to 0° C. under a nitrogen atmosphere. After adding 0.34 ml of phenyl chlorocarbonate to the solution, it was stirred at room temperature for 2 hours. Ethyl acetate and water were added to the reaction solution, and the precipitated solid was filtered out to obtain 590 mg of the title compound as light brown crystals (56% yield).
