실험 절차
A solution of 1-(4-iodophenyl)ethanone (55.9 mmol) in dioxane (160 mL) was cooled to 10° C. Bromine (1.1 equiv, 61.6 mmol) was added dropwise to the reaction mixture. After 10 min, the cooling bath was removed and the reaction mixture was stirred at room temperature. After 1.5 h, the reaction mixture was concentrated in vacuo, poured into water (100 mL), and extracted with (3×100 mL) ethyl acetate. The combined organic layers were dried over sodium sulfate and concentrated in vacuo to a tan solid (18.2 g) which was used directly in the next step.
