Vorschrift

Dissolving 19 g (47 mmol) of 4-anthracen-9-yl-2,6-diphenyl-pyrimidine obtained in the foregoing step (2) into 200 milliliter of N,N-dimethylformamide, and adding 9.2 g (52 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 4-(10-bromo-anthracen-9-yl)-2,6-diphenyl-pyrimidine (yield: 66%).
