The 7-benzyloxy-6-cyano-4-(3-fluoro-4-aminophenoxy)quinoline (9.45 g) synthesized in Production Example 8 was dissolved in dimethylformamide (70 ml) and pyridine (5.9 ml), and the mixture was cooled to 0° C. under a nitrogen atmosphere. After adding phenyl chlorocarbonate (3.4 ml), the mixture was stirred for 2 hours. Water was added to the reaction solution, and the precipitated crystals were filtered out and triturated in tetrahydrofuran and toluene to obtain 6.93 g of the title compound as light brown crystals (56% yield).
