実験手順

A mixture of 5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxylic acid (300 mg, 0.67 mmol), HATU (281 mg, 0.74 mmol) and N,N-diisopropylethylamine (258 mg, 2.0 mmol) in anhydrous DMF (10 ml) was stirred at room temperature for 10 minutes, followed by addition of ethyl 5-aminovalerate hydrochloride (145 mg, 0.80 mmol). The mixture was stirred for another 10 minutes and poured into 100 ml of water. 2M HCl was added dropwise until pH=4. The precipitates were filtered, washed with water and dried in vacuo to give the crude, which was purified by silica gel chromatography eluting with 3˜5% of methanol in chloroform to give ethyl 5-{[(5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}pentanoate as white solid. Yield: 288 mg, 75%.
