Reaction Steps

Then, to a mixed solution of 100.6 g of 7-t-butyl-1-(4-chlorophenyl)pyrene, and 1638 ml of tetrahydrofuran was added 53.5 g of N-bromosuccinimide under a nitrogen stream. This mixed solution was stirred at 30° C. for about 5 hours, and concentrated, 984 ml of methanol was added, and the mixture was stirred for about 1 hour, and filtered. To the resulting solid was added 539 ml of hexane, and the mixture was heated and stirred for about 1 hour, and filtered. After the resultant was vacuum dried, 112.0 g of 1-bromo-7-t-butyl-3-(4-chlorophenyl)pyrene was obtained.
