Reaction Steps

To a stirred solution of ethyl 4-{[(5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}butanoate (45 mg, 0.078 mmol) in 10 ml of THF was added 3 ml of 1M NaOH (3.0 mmol). The mixture was heated at 60° C. for 3 hours, cooled to room temperature and poured into 100 ml of water. 2M HCl was added until pH=5. The precipitates were filtered, washed with water, and dried to give 4-{[(5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}butanoic acid as grey solid. Yield: 40 mg, 93%.
