To a mixture of 6-ethyl-3-{[2-methyl-4-(morpholin-4-yl)phenyl]amino}-5-(3-nitrophenoxy)pyrazine-2-carboxamide (145 mg), ethanol (2 mL), and tetrahydrofuran (6 mL) was added 10% palladium-supported carbon (50% wet product) (30 mg), followed by stirring for 5 hours under a hydrogen gas atmosphere (1 atm). The reaction mixture was filtered through celite and then the solvent was evaporated under reduced pressure to obtain 5-(3-aminophenoxy)-6-ethyl-3-{[2-methyl-4-(morpholin-4-yl)phenyl]amino}pyrazine-2-carboxamide (135 mg) as a solid.
