Procedure
Into a reactor were introduced 2.50 g (9.82 mmol) of the 1,1-bis(4-methoxyphenyl)propene and 25 mL of 1,2-dichloroethane under a nitrogen atmosphere. The contents were cooled to −20° C. A mixture of 1.57 g (9.82 mmol) of bromine and 13 mL of 1,2-dichloroethane was gradually added dropwise thereto, and the resultant mixture was stirred overnight at room temperature. This 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 to obtain 3.26 g (100%) of the target compound as a light-yellow oily substance.
