Procedure

To a stirred solution of methyl 4-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-2-carboxylate (220 mg, 0.48 mmol) in THF/MeOH (3 ml/10 ml) was added 1M NaOH (4.0 ml, 4.0 mmol). The mixture was heated at 70° C. for 2 hours, cooled to room temperature and poured into 100 ml of water. 1M HCl was added until pH=4 and the resulting precipitates were filtered, washed with water and dried in vacuo to give 4-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-2-carboxylic acid.
