Procedure

To a stirred suspension of tert-butyl {2-[({7-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]thieno[3,2-b]pyridin-2-yl}carbonyl)amino]ethyl}carbamate (488 mg, 0.82 mmol) in 10 ml of dichloromethane was added 5 ml of trifluoroacetic acid. The mixture was stirred at room temperature for one hour 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)-7-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]thieno[3,2-b]pyridine-2-carboxamide as brown solid. Yield: 400 mg, 99%.
