Reaction Steps

Part B: To a solution of 2-(4-chlorophenyl)-1-(2,4-dichlorophenyl)ethanone (2.82 gram, 9.42 mmol) in benzene (25 mL) is added bromine (0.48 mL, 1.49 gram, 9.31 mmol) and the resulting solution is stirred at room temperature for two hours. Dichloromethane is added and the resulting solution is washed with aqueous NaHCO3 solution. The organic layer is dried over MgSO4, filtered and evaporated in vacuo to give 3.55 gram (quantitative yield) of 2-bromo-2-(4-chlorophenyl)-1-(2,4-dichlorophenyl)ethanone as a yellow oil (purity˜95% according to HPLC analysis). 1H-NMR (200 MHz, CDCl3): δ 7.00-7.50 (m, 7H), 6.16 (s, 1H).
