실험 절차

To a stirred solution of methyl 5-(4-{3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-1H-pyrrole-3-carboxylate (1.30 g, 3.12 mmol) in a mixture of solvents THF/MeOH (10 ml/10 ml) was added 2 ml of 5M NaOH (10 mmol) solution. The mixture was heated in a 68° C. bath for 8 hours, cooled to room temperature and poured into 200 ml of water. 2M HCl was added until pH=3. The resulting precipitates were filtered, washed with water, and dried in vacuo to give 5-(4-{3-[(3-methyl-2-furoyl)amino]phenoxy}pyridin-2-yl)-1H-pyrrole-3-carboxylic acid as white solid. Yield: 1.20 g, 95%.
