실험 절차

Methyl 2-[4-(2-bromo-5-nitrobenzyloxy)-2-fluorophenyl]-1-cyclohexylbenzimidazole-5-carboxylate (2.0 g) obtained in Example 336, 4-chlorophenylboronic acid (590 mg) and tetrakis(triphenylphosphine)palladium (396 mg) were suspended in dimethoxyethane (40 ml), and saturated aqueous sodium hydrogencarbonate solution (20 ml) was added, which was followed by refluxing under heating for 1 hr. The reaction mixture was allowed to cool, water was added and the mixture was extracted with chloroform. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel flash chromatography (n-hexane:ethyl acatate=2:1) to give the title compound (1.9 g, yield 90%).
