Procedure

To a stirred solution of methyl 4-[4-(4-aminophenoxy)pyridin-2-yl]thiophene-2-carboxylate (500 mg, 1.53 mmol) in anhydrous THF (10 ml) was added 2-fluoro-5-methyl-phenylisocyanate (255 mg, 1.68 mmol). The mixture was stirred at room temperature for one hour and poured into 200 ml of water. The resulting precipitates were filtered, washed with water and dried in vacuo to give the crude, which was purified by silica gel chromatography eluting with 3-5% MeOH/CHCl3 to give methyl 4-{4-[4-({[(2-fluoro-5-methylphenyl)amino]carbonyl}amino)phenoxy]pyridin-2-yl}thiophene-2-carboxylate as off-white solid. Yield: 560 mg, 76%.
