Reaction Steps

22.5 g (50 mmol) of 9,10-bis(2,6-dimethoxyphenyl)anthracene are dissolved in 500 ml of NMP, 107.1 g (800 mmol) of lithium iodide (anhydrous) are added, and the mixture is stirred at 190° C. for 48 h. After cooling, the reaction mixture is introduced into 2000 ml of 1N HCl with stirring. The precipitated solid is filtered off and washed three times with 200 ml of water each time and then three times with 100 ml of ethanol each time. Finally, the product is recrystallised from DMSO (15 ml/g) and dried under reduced pressure. Yield: 16.9 g, 85.7% of theory, purity: 99.0% according to HPLC.
