الإجراء التجريبي

4.05 g of 10-(2-naphthyl)benzo[g]chrysene and 400 mL of acetic acid were placed in a flask. 1.92 g of bromine was added, and the resultant was heated with stirring at 100° C. for 8 hours. After cooling to room temperature, the reaction solution was poured to 1 L of ice water. Deposited solids were separated by filtration, and washed with water and then with methanol, and dried. The thus obtained solids were purified by means of silica gel column chromatography, whereby 4.35 g (yield: 90%) of 3-bromo-10-(2-naphthyl)benzo[g]chrysene was obtained.
