Procedure

To a stirred solution of 5-[4-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrole-3-carboxylic acid (100 mg, 0.22 mmol) in 10 ml of anhydrous DMF were added HATU (100 mg, 0.26 mmol) and N,N-diisopropylethylamine (85 mg, 0.66 mmol). The mixture was stirred at room temperature for 10 minutes, followed by addition of β-alanine methyl ester hydrochloride (46 mg, 0.33 mmol). The mixture was stirred for another 5 minutes and poured into 100 ml of water. 2M HCl was added dropwise with vigorous stirring until pH=4. The precipitates were filtered, washed with water and dried in vacuo to give methyl 3-[({5-[4-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrol-3-yl}carbonyl)amino]propanoate as white solid. Yield: 110 mg, 92%.
