실험 절차

After 6.0 g (23.7 mmol) of 9-phenylanthracene was dissolved in 80 mL of carbon tetrachloride, a solution of 3.80 g (21.1 mmol) of bromine dissolved in 10 mL of carbon tetrachloride was dripped through a dropping funnel into the reaction solution. After the dripping, the solution was stirred at room temperature for one hour. After the reaction, a sodium thiosulfate aqueous solution was added to stop the reaction. An organic layer was washed with a sodium hydroxide (NaOH) aqueous solution and a saturated saline solution and dried with magnesium sulfate. After the solution was filtered naturally, the filtrate was concentrated, dissolved in toluene, and filtered through Florisil, Celite, and alumina. When the filtrate was concentrated and recrystallized with dichloromethane and hexane, 7.0 g of a light yellow solid of 10-bromo-9-phenylanthracene that was an object was obtained (yield: 89%).
