Reaction Steps

A mixture of 2-chloro-1H-benzimidazole (5.6 g), 4-bromophenol (9.87 g) and triethylamine (19.89 ml) was stirred at 120° C. for 15 hr, and ethyl acetate was added. The reaction mixture was washed with 1 M aqueous sodium hydroxide solution and saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. A solid precipitated from the residue was collected by filtration to give the title compound (5.77 g).
