Reaction Conditions

Reaction Steps

To a mixed solution of 120 g (content 79.2%) of 2-t-butylpyrene, and 3000 ml of tetrahydrofuran was added 69.66 g of N-bromosuccinimide under a nitrogen stream. This mixed solution was stirred at 30° C. for about 3 hours, and concentrated, 500 ml of methanol was added, and the mixture was stirred for about 1 hour, and filtered. To the resulting solid was added 500 ml of hexane, and the mixture was heated and stirred for about 1 hour, and filtered. After the resultant was vacuum dried, 106.9 g of 1-bromo-7-t-butylpyrene was obtained.
