Reaction Steps

2-n-Butyl benzimidazole (3.00 g, 17.22 mmol) was mixed with powdered potassium carbonate (2.62 g, 19 mmol) and diluted with 25 mL dimethylformamide. To this was added ethyl bromoacetate (18.94 mmol). The reaction mixture was stirred at ambient temperature overnight and poured into 150 mL of water. The resulting crystals were filtered, and recrystallized from hexane to give 2.26 g (50%) of a solid; mp 70°-71° C.
