実験手順

Pyridine (50 ml) was mixed with tetrahydrofuran (40 ml) and cooled to 10° C. A solution of phenyl chloroformate (4.83 g) in acetonitrile (50 ml) and a solution of 1-[4-(2-aminopyridin-4-yloxy)-2-fluorophenylcarbamoyl]cyclopropanecarboxylic acid benzyl ester (10.00 g) in tetrahydrofuran (80 ml) were added dropwise to the tetrahydrofuran-pyridine solution over a period of 2 hours at 10° C. At this time, the amounts of the phenyl chloroformate-acetonitrile solution and the 1-[4-(2-aminopyridin-4-yloxy)-2-fluorophenylcarbamoyl]cyclopropanecarboxylic acid benzyl ester/tetrahydrofuran solution added dropwise were adjusted to the constant rate so that each solution was added dropwise over a period of 2 hours. The crystals were precipitated while the solutions were added dropwise. After completing the dropwise addition, the completion of reaction was confirmed using an HPLC apparatus. Subsequently, a mixed solution of water (10 ml) and acetonitrile (50 ml) was added to the reaction mixture. The crystals were collected by filtration and washed with a mixed solution of tetrahydrofuran (15 ml)-acetonitrile (15 ml) and dried under reduced pressure to give the title compound (12.74 g). Apparent yield 98.0%, purity 94.6% (HPLC area percentage).
