Procedure

To a stirred suspension of 4-(2-(1H-pyrrol-2-yl)pyridin-4-yl)aniline TFA salt (60 mg, 0.17 mmol) in anhydrous THF (10 ml) was added 2-fluoro-5-methyl-phenylisocyanate (48 mg, 0.32 mmol) and N,N-diisopropylethylamine (40 mg, 0.31 mmol). After 1 hour, the reaction mixture was evaporated and purified by silica gel chromatography with 2-3% MeOH/CHCl3 to give 1-(2-fluoro-5-methylphenyl)-3-{4-[2-(1H-pyrrol-2-yl)pyridin-4-yl]phenyl}urea as off-white solid. Yield: 28 mg.
