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 (120 mg, 0.26 mmol), HATU (110 mg, 0.29 mmol) and N,N-diisopropylethylamine (100 mg, 0.78 mmol) in anhydrous DMF (10 ml) was stirred at room temperature for 10 minutes, followed by addition of L-glutamic acid dimethyl ester hydrochloride (66 mg, 0.31 mmol). The mixture was heated at 50° C. for 15 minutes, cooled to room temperature and poured into 100 ml of water with vigorous stirring. 2M HCl was added dropwise until pH=4. The precipitates were filtered, washed with water and dried in vacuo to give dimethyl 2-{[(5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}pentanedioate as white solid. Yield: 130 mg, 81%.
