Vorschrift

23.1 g of 9-(naphthalene-2-yl)anthracene was dispersed into 250 ml of DMF (dimethylformamide), and then 14.9 g of NBS (N-bromosuccinimide) in DMF solution (150 ml) was dropped therein. After stirred at room temperature for 7 hours, it was left over a night. 200 ml of water was added thereto, and then the crystal precipitated was separated by filtration. Subsequently it was washed by ethanol adequately, followed by drying, and 28.8 g of 9-bromo-10-(naphthalene-2-yl)anthracene of beige color crystal was obtained (Yield: 99%).
