Reaction Steps

To a stirred solution of 143.6 g (0.5 mole) of 2-(4-bromomethylphenyl)benzimidazole and 42.0 g (0.5 mole) of sodium bicarbonate in 85% aqueous acetone is added 66.0 g (0.5 mole) of dimethylsulfate dropwise. The mixture is stirred at 40° C. for about 3 hours until thin-layer chromatography indicates that the reaction is complete. The solvent is removed in vacuo, and the solid product is washed with water to eliminate sodium salts and purified by recrystallization from benzene.
