A mixed solution of 13.3 g of the above-mentioned 9-(4-tert-butylphenyl)anthracene, 7.52 g of bromine and 300 ml of carbon tetrachloride was heated to reflux under nitrogen atmosphere for 1 hour. After cooling the mixed solution to room temperature, 200 ml of water was injected thereto to extract 200 ml of dichloromethane therefrom. The organic layer was washed twice in 200 ml of water, dried by magnesium sulfate and thereafter concentrated by evaporation. The organic layer was washed twice in 100 ml of hexane and vacuum dried to thereafter obtain 16.09 g of 9-bromo-10-(4-tert-butylphenyl)anthracene.
