実験手順

Dissolving 20 g (81 mmol) of 4′-iodo acetophenone into 200 milliliter of acetic acid, and adding 12.8 g (81 mmol) of bromine while cooling with ice, stirred at the temperature of 15° C. for 3 hours. After the color of bromine disappeared, adding water and separating the precipitated solids by filtration, thereby obtained 27 g of crude 2-bromo-4′-iodo acetophenone.
