Reaction Steps

A solution of 2-ethyl-4-(4-methoxybenzyloxy)-1H-benzimidazole (282 mg), ethyl bromoacetate (184 mg) and potassium carbonate (414 mg) in dimethylformamide (3 ml) was stirred for 2 hours, and to the reaction mixture were added ethyl acetate and water. The separated organic layer was washed with brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by flash chromatography (ethyl acetate:n-hexane=1:2 to 2:1, v/v) to give 1-ethoxycarbonylmethyl-2-ethyl-4-(4-methoxybenzyloxy)-1H-benzimidazole (245 mg) as white powder.
