실험 절차
65.5 g (0.36 mole) of 4-chlorophenyl isopropyl ketone are dissolved in 200 ml of chloroform, and 1 ml of hydrogen bromide/glacial acetic acid is added. 57.5 g (0.36 mole) of bromine are then slowly added dropwise at 30° C. and the mixture is subsequently stirred at room temperature for 30 minutes. The mixture is concentrated in vacuo to give 86.6 g (92% of theory) of crude 2-bromo-prop-2-yl 4-chlorophenyl ketone as an oil, which is further reacted directly.
후처리
