Reaction Steps

To a stirred solution of methyl[({5-[4-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrol-3-yl}carbonyl)amino]acetate (110 mg, 0.21 mmol) in a mixture of solvents THF/MeOH (5 ml/5 ml) was added 1M NaOH solution (1 ml, 1 mmol). The mixture was stirred at room temperature for 1 hour, and poured into 100 ml of water. 2M HCl was added until pH=4. The precipitates were filtered, washed with water and dried in vacuo to give [({5-[4-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrol-3-yl}carbonyl)amino]acetic acid as white solid. Yield: 100 mg, 93%.
