Procedure

To a stirred solution of 5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxylic acid (300 mg, 0.65 mmol) in 10 ml of anhydrous DMF were added HATU (296 mg, 0.78 mmol) and N,N-diisopropylethylamine (185 mg, 1.43 mmol). The mixture was stirred at room temperature for 10 minutes, followed by addition of tert-butyl 1-piperazinecarboxylate (182 mg, 0.98 mmol). The mixture was stirred for another 10 minutes and poured into 100 ml of water. 1M HCl was added slowly until pH=5. The precipitates were filtered, washed with water and dried in vacuo to give tert-butyl 4-[(5-{4-[3-fluoro-4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrol-3-yl)carbonyl]piperazine-1-carboxylate as white solid. Yield: 290 mg, 84%.
