Procedure

To a stirred suspension of tert-butyl (2-{[(5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}ethyl)carbamate (355 mg, 0.60 mmol) in 10 ml of methylene chloride was added 5 ml of trifluoroacetic acid. The mixture was stirred at room temperature for 30 minutes and evaporated to dryness under reduced pressure. The residue was re-dissolved in MeOH (5 ml) and poured into 100 ml of water with vigorous stirring. Saturated NaHCO3 solution was added until pH=8˜9. The precipitates were filtered, washed with water and dried in vacuo to give N-(2-aminoethyl)-5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxamide as brown solid. Yield: 260 mg, 88%.
