To a solution of m-chlorostyrene (5.70 g, 41.0 mmol) and acetic acid (2.33 mL, 40.9 mmol) in dioxane (33 ml) and H2O (78 ml) at 0° C. was added N-bromosuccinimide (8.02 g, 45.0 mmol) in three portions. The reaction was allowed to warm to R.T. After 4 hours, 2N NaOH (60 ml) was added and the reaction was allowed to stir at RT overnight. The reaction mixture was partitioned between water and EtOAc, and the aqueous phase was extracted with EtOAc. The combined organic phases were washed with brine, dried (Na2SO4), filtered and evaporated in vacuo to give 6.20 g of a slightly tinted oil which was used without further purification.
