Reaction Steps

To a suspension of 3-(4-fluorophenyl)benzoic acid (151 mg) and 3-(1,2-dimethylimidazol-5-yl)aniline (131 mg) in dichloromethane (5 ml) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (201 mg) and 4-dimethylaminopyridine (43 mg). The mixture was stirred at ambient temperature for 18 hours and diluted with dichloromethane. The solution was washed with water and brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by a silica gel column chromatography eluting with 3% methanol in dichloromethane to give N-[3-(2,3 dimethyl-3H-imidazolyl)-phenyl]-4′-fluoro-biphenyl-3-carboxamide (240 mg, 88.9%).
