Procedure

To a stirred solution of 4-(2-Chloro-pyridin-4-ylsulfanyl)-phenylamine (300 mg, 1.27 mmol) in anhydrous THF (10 ml) was added 2-fluoro-5-methyl-phenylisocyanate (210 mg, 1.39 mmol). The mixture was stirred at 60° C. for 5 hours, and poured into 100 ml of water. The precipitates were filtered, washed with water (50 ml), and dried to give the crude, which was purified by silica gel chromatography eluting with 2-3% MeOH/CHCl3 to give 1-[4-(2-Chloro-pyridin-4-ylsulfanyl)-phenyl]-3-(2-fluoro-5-methyl-phenyl)-urea as white solid. Yield: 410 mg, 83%.
