Procedure

To a stirred solution of 5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxylic acid (150 mg, 0.34 mmol) in 10 ml of anhydrous DMF were added methyl 4-bromobutanoate (123 mg, 0.68 mmol) and potassium carbonate (94 mg, 0.68 mmol). The mixture was heated at 60 C. for 2 hours, cooled to room temperature, and poured into 100 ml of water with vigorous stirring. The precipitates were filtered, washed with water and dried in vacuo to give the crude, which was purified by silica gel chromatography eluting with 2˜3% of methanol in chloroform to give 4-methoxy-4-oxobutyl 5-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}-1H-pyrrole-3-carboxylate as off-white solid. Yield: 130 mg, 71%.
