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 (400 mg, 0.86 mmol), HATU (380 mg, 1.0 mmol) and N,N-diisopropylethylamine (244 mg, 1.9 mmol) in anhydrous DMF (10 ml) was stirred at room temperature for 10 minutes, followed by addition of N-Boc-1,3-propanediamine (174 mg, 1.0 mmol). The mixture was stirred for another 10 minutes and poured into 100 ml of water with vigorous stirring. 1M HCl was added dropwise until pH=5. The precipitates were filtered, washed with water and dried in vacuo to give tert-butyl (3-{[(5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}propyl)carbamate as white solid. Yield: 500 mg, 94%.
