Versuchsvorschrift

1-[2-Fluoro-4-(2-{[4-(4-methylpiperazin-1-yl)piperidine-1-carbonyl]amino}pyridin-4-yloxy)phenylcarbamoyl]cyclopropanecarboxylic acid benzyl ester hydrochloride (2 g) was dissolved in water (20 ml) and ethyl acetate (20 ml), and a 2N aqueous solution of sodium hydroxide (4 ml) was added, and the layers were separated. The organic layer was washed with water and concentrated. Addition of tetrahydrofuran and subsequent concentration was repeated three times. The residue was dissolved in a mixed solvent of tetrahydrofuran (8 ml) and water (1.6 ml), and palladium on carbon (200 mg) was added, and the mixture was stirred at room temperature under a hydrogen atmosphere (0.2 MPa) for 5 hours. Tetrahydrofuran (4 ml) and methanol (6 ml) were added to the reaction mixture, which was filtered. The residue was washed with 90% aqueous methanol (3 ml). Tetrahydrofuran (12 ml) and the seed crystals obtained in (Method 1) were added to the filtrate, and the mixture was stirred at room temperature for 1 hour. Ethyl acetate (32 ml) was added, and the mixture was stirred for 14 hours. The crystals were filtered and dried to give the title compound (1.2 g) as white crystals.
