Reaction Steps

To a stirred solution of methyl 3-[({5-[4-(2-fluoro-5-{[(3-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrol-3-yl}carbonyl)amino]propanoate (80 mg, 0.16 mmol) in a mixture of THF/MeOH (5 ml/5 ml) was added 1M NaOH solution (1 ml, 1 mmol). The mixture was stirred at room temperature for 3 hours and poured into 50 ml of water. 1M HCl was added dropwise until pH=4. The precipitates were filtered, washed with water and dried in vacuo to give 3-[({5-[4-(2-fluoro-5-{[(3-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrol-3-yl}carbonyl)amino]propanoic acid as white solid. Yield: 70 mg, 90%.
