Reaction Steps

To a stirred solution of N-(2,2-diethoxyethyl)-5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxamide (550 mg, 0.95 mmol) in 10 ml of THF was added 2 ml of 2M HCl. The mixture was stirred at room temperature under nitrogen for overnight, and poured into 100 ml of water with vigorous stirring. Saturated NaHCO3 solution was added until pH=8. The precipitates were filtered, washed with water, and dried to give 5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-N-(2-oxoethyl)-1H-pyrrole-3-carboxamide as off-white solid. Yield: 475 mg, 99%.
