Reaction Steps

2.5 g of 4-bromo-6-methoxy-2-phenyl-1H-benzimidazole and 2.24 g of 4-(methylbenzene)boronic acid were stirred with 1.5 g of anhydrous copper(II) acetate and about 3 g of molecular sieve in 35 ml of pyridine for 7 hours at 100° C. After dichloromethane and Celite were added, it was concentrated by evaporation and chromatographed on silica gel with a hexane/ethyl acetate mixture.
