실험 절차
A solution of bromine (0.68 mL, 13.3 mmol) in chloroform (13 mL) was added dropwise over a 35 minute period to a stirred solution of 1-(3-bromo-4-methylphenyl)ethanone (2.96 g, 13.9 mmol) in chloroform (40 mL) at 0° C. After the addition, the ice-bath was removed and the mixture was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure to give an oil which crystallized to give the title compound (4.11 g, 95%) as an orange solid.
