Reaction Steps

A mixture of 4-{[(5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}butanoic acid (60 mg, 0.1 mmol), HATU (50 mg, 0.13 mmol) and N,N-diisopropylethylamine (43 mg, 0.33 mmol) in anhydrous DMF (8 ml) was stirred at room temperature for 10 minutes, followed by addition of (R)-3-pyrrolidinol (14 mg, 0.16 mmol). The mixture was stirred for another 10 minutes and poured into 100 ml of water. 2M HCl was added dropwise until pH=4˜5. The precipitates were filtered, washed with water and dried in vacuo to give 5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-N-[4-(3-hydroxypyrrolidin-1-yl)-4-oxobutyl]-1H-pyrrole-3-carboxamide as white solid. Yield: 40 mg, 59%.
