Vorschrift

First, 33.0 g of 2,6-diphenylanthracene were dissolved in 200 mL of N,N-dimethylformamide under heat, and then a solution of 18.0 g of N-bromosuccinimide in 20 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 1 L 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, 33.5 g of 9-bromo-2,6-diphenylanthracene were obtained (in 82% yield).
