Reaction Steps
To a solution of a sodium salt, prepared from 1.22 g of 2,4,5-tribromoimidazole and 0.16 g of 60% oil-based sodium hydride, in 5 ml of N,N-dimethylformamide was added dropwise 1.23 g of 4-bromobutoxymethyl bromide at room temperature. After stirring at room temperature for 3 hours, 50 ml of water was added to the reaction mixture which was then extracted with three 30-ml portions of ether. The ether layer was dried over magnesium sulfate and concentrated. The oily product obtained was purified by column chromatography on silica gel to obtain 0.74 g of 1-(4-bromobutoxymethyl)-2,4,5-tribromoimidazole.
