Reaction Steps
A mixture of 5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxylic acid (300 mg, 0.65 mmol), HATU (296 mg, 0.78 mmol) and N,N-diisopropylethylamine (185 mg, 1.43 mmol) in anhydrous DMF (10 ml) was stirred at room temperature for 10 minutes, followed by addition of tert-butyl (2-aminoethyl)carbamate (125 mg, 0.78 mmol). The mixture was stirred for another 10 minutes and poured into 100 ml of water. 1M HCl was added dropwise until pH=5. The precipitates were filtered, washed with water and dried in vacuo to give tert-butyl (2-{[(5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}ethyl)carbamate as white solid. Yield: 350 mg, 89%.
