Procedure

A mixture of 5-{4-[3-fluoro-4-({[(3-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxylic acid (500 mg, 1.1 mmol), HATU (500 mg, 1.32 mmol) and N,N-diisopropylethylamine (426 mg, 3.3 mmol) in anhydrous DMF (8 ml) was stirred at room temperature for 10 minutes, followed by addition of L-Glutamic acid 5-tert-butyl 1-methyl ester hydrochloride (334 mg, 1.32 mmol). The mixture was stirred for another 10 minutes and poured into 200 ml of water. 2M HCl was added dropwise until pH=5. 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% MeOH/CHCl3 to give (S)-5-tert-butyl 1-methyl 2-{[(5-{4-[3-fluoro-4-({[(3-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]amino}pentanedioate as off-white solid. Yield: 380 mg, 52%.
