The mixture was stirred at room temperature for 10 minutes, followed by addition of L-glutamic acid dimethyl ester hydrochloride (108 mg, 0.51 mmol). The mixture was stirred for another 10 minutes and poured into 100 ml of water. 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% methanol in chloroform to give dimethyl 2-{[(5-{4-[3-fluoro-4-({[(3-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}pentanedioate as white solid. Yield: 120 mg, 59%.
