To a stirred solution of methyl 5-[4-({3-[(3-methyl-2-furoyl)amino]phenyl}amino)pyridin-2-yl]-1H-pyrrole-3-carboxylate (10 mg, 0.024 mmol) in a mixture of solvents THF/MeOH (5 ml/5 ml) was added 2 ml of 1M NaOH (2 mmol) solution. The mixture was heated in a 60° C. bath for 16 hours, cooled to room temperature and poured into 100 ml of water. 2M HCl was added until pH=5. The resulting precipitates were filtered, washed with water, and dried in vacuo to give 5-[4-({3-[(3-methyl-2-furoyl)amino]phenyl}amino)pyridin-2-yl]-1H-pyrrole-3-carboxylic acid as light brown solid. Yield: 2 mg.
