To a solution of benzyl (2-fluoro-4-{2-[(4-pyrrolidin-1-ylpiperidine-1-carbonyl)amino]pyridin-4-yloxy}phenyl)carbamate (91 mg) in tetrahydrofuran (10 ml) was 10% palladium carbon (36.4 mg), followed by stirring under a hydrogen atmosphere at room temperature for 3.5 hrs. Ethanol (5.0 ml) was added thereto, followed by stirring under a hydrogen atmosphere at room temperature for 1.5 hrs. The reaction mixture was filtered to remove the catalyst, and washed with a small amount of tetrahydrofuran to give a solution of the titled compound in tetrahydrofuran. The solution was concentrated to almost dryness, which was then used for succeeding reactions without further purification.
