Reaction Conditions:

with sulfuric acid;sodium bromide;dibenzoyl peroxide in tetrachloromethane at 70; for 7 h;

Steps:

22 Preparation of 3-(4-bromophenoxy)bromopropane

Start stirring after dropping into carbon tetrachloride 200ml in the reaction kettle, add propenyl (4-bromophenyl) ether 42.6g successively, benzoyl peroxide 1g and sodium bromide 35.7g, slowly add dropwise when warming up to 70°C Sulfuric acid 18g, incubated for 5h after the dropwise addition, cooled to room temperature after the reaction was completed, then the organic layer was washed with sodium carbonate aqueous solution, washed with water until neutral, dried and concentrated under reduced pressure to obtain 3-(4-bromophenoxy)bromide Propane 55.9, 95% yield.
