Vorschrift

Dissolving 2.2 g (6.2 mmol) of 2-(4-anthracen-9-yl-phenyl) quinoxaline obtained in the foregoing step (2) into 20 milliliter of N,N-dimethylformamide, and adding 1.2 g (6.7 mmol) of N-bromosuccinimide, stirred at room temperature for 8 hours. After completion of the reaction, precipitated solids were separated by filtration and washed with water and methanol, thereby obtaining 14.9 g of 2-[4-(10-bromo-anthracen-9-yl)-phenyl]-quinoxaline (yield: 78%).
