3.0 Grams (0.02 mole) of 1-p-tolylcyclopropane-1-carbonitrile and 0.1 g (0.0004 mole) of benzoyl peroxide were dissolved in 50 ml of carbon tetrachloride, and 3.2 g of bromine was added dropwise over 30 minutes under reflux. After completion of the addition, reaction was continued for further 30 minutes. After cooling the reaction solution, carbon tetrachloride was removed by evaporation to obtain 4.4 g of 1-(4-bromomethylphenyl)cyclopropane-1-carbonitrile.
