Vorschrift

9-(4-Bromophenyl)anthracene (6.3 g, 19 mmole) was dissolved in anhydrous dimethylformamide (DMF) (100 ml). To the resultant solution, a solution (15 ml) of NBS (3.7 g, 21 mmole, 1.1 eq) in anhydrous DMF was added and the obtained mixture was stirred at the room temperature for 7 hours and left standing for one night. After the reaction mixture was diluted with water (30 ml), the formed solid was separated by filtration and washed with methanol and a yellow solid (6.0 g, 77%) was obtained.
