Reaktionsschritte

3.33 g (10 mmol) of 9-bromo-10-phenylanthracene was dissolved in 80 ml of tetrahydrofuran (abbreviation: THF), and the temperature was lowered to −78° C. 7.5 ml (12.0 mmol) of n-BuLi (1.6M) was dropped into the reaction solution by a dropping funnel, and it was stirred for 1 hour. A solution in which 5 g (20.0 mmol) of iodine was dissolved in 20 ml of THF was dropped and stirred for 2 hours at −78° C. After reaction, a sodium thiosulfate water solution was added to stop the reaction. An organic layer was washed with a sodium thiosulfate water solution and a saturated saline and dried with magnesium sulfate. After the natural filtration, the filtrate was concentrated and the obtained solid was recrystallized by ethanol. Then, 3.1 g of a light-yellow solid of 9-iodo-10-phenylanthracene, which was the intended object, was obtained with a yield of 83% (synthetic scheme of (b-5)).
