Reaction Steps

Part D: Crude 1-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-1H-imidazole-4-carbonyl chloride (919 mg, ˜2.39 mmol), 1-aminopiperidine (0.469 g, 4.69 mmol) and triethylamine (0.363 g, 3.59 mmol) are dissolved in dichloromethane and stirred for one hour at room temperature. The mixture is washed with a saturated aqueous NaHCO3 solution (3×20 mL), dried over Na2SO4 and concentrated in vacuo and further purified by column chromatography (ethyl acetate, silicagel) to give 1-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-N-(piperidin-1-yl)-1H-imidazole-4-carboxamide (356 mg, 26% yield (based on ethyl 1-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-1H-imidazole-4-carboxylate). Mass Spectrometry (MS): 449.
