Vorschrift

First, 9.09 g of 2,6-diphenyl-9-(2-naphthyl)anthracene were dissolved in 100 mL of N,N-dimethylformamide under heat, and then a solution of 3.91 g of N-bromosuccinimide in 10 mL of N,N-dimethylformamide was added to the solution. The mixture was stirred at 60° C. for 6 hours under heat. After having been cooled to room temperature, the reaction solution was poured into 500 mL of water. The resultant solid was sequentially washed with methanol, water, and methanol. After that, the solid was repeatedly recrystallized with toluene and hexane and washed. Thus, 8.55 g of 9-bromo-2,6-diphenyl-10-(2-naphthyl)anthracene were obtained (in 80% yield).
