実験手順

Part C: To 2-(2,4-dichlorophenyl)-5-methyl-1-(4-methoxyphenyl)-1H-imidazole-4-carboxylic acid (1.00 gram, 2.65 mmol) in dry acetonitrile (25 mL) is successively added diisopropylethylamine (DIPEA) (1.02 mL, 2.2 molar equivalents), O-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluoro-phosphate (HBTU) (1.21 gram, 1.2 molar equivalents) and the resulting solution is stirred for 15 minutes. Cyclohexylamine (0.36 mL, 1.2 molar equivalents) is added. After stirring for 50 hours, the resulting mixture is concentrated in vacuo. The residue is dissolved in dichloromethane and an aqueous NaHCO3 solution is added. The dichloromethane layer is collected, dried over Na2SO4, filtered and concentrated in vacuo. The residue is further purified by column chromatography (gradient:dichloromethane=>dichloromethane/methanol=99/1 (v/v), silicagel) to give N-(1-cyclohexyl)-2-(2,4-dichlorophenyl)-5-methyl-1-(4-methoxyphenyl)-1H-imidazole-4-carboxamide (1.03 gram, 85% yield). Melting point: 160-161° C.
