Reaction Steps
Into a reactor were introduced 8.81 g (39.6 mmol) of the 1,1-diphenyl-3-methylbutene and 35 mL of 1,2-dichloroethane under a nitrogen atmosphere. The contents were cooled to 0° C., and 6.33 g (39.6 mmol) of bromine was gradually added dropwise thereto. This mixture was stirred at room temperature for 1 hour. The resultant reaction mixture was washed with saturated aqueous sodium hydrogen carbonate solution and saturated aqueous sodium chloride solution and then dried with anhydrous magnesium sulfate. Thereafter, the solvent was removed under reduced pressure. The concentrate was recrystallized from ethanol and ethyl acetate to obtain 8.64 g (72%) of the target compound as white crystals.
