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]piperazin-1-yl}acetate (175 mg, 0.28 mmol) in MeOH (8 ml) was added 1M NaOH solution (1 ml, 1 mmol). The mixture was stirred at room temperature for 16 hours and poured into 50 ml of water. 1M HCl was added dropwise with vigorous stirring until pH=7. The precipitates were filtered, washed with water and dried in vacuo to give {4-[5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]piperazin-1-yl}acetic acid as white solid. Yield: 160 mg, 96%.
