To a stirred solution of methyl {1-[(5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]piperidin-4-yl}acetate (50 mg, 0.085 mmol) in THF/MeOH (5 ml/5 ml) was added 1M NaOH solution (3 ml, 3 mmol). The mixture was stirred at room temperature for one hour, and poured into 50 ml of water. 2M HCl was added until pH=4. The resulting precipitates were filtered, washed with water, and dried in vacuo to give {1-[(5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]piperidin-4-yl}acetic acid as white solid. Yield: 47 mg, 96%.
