Reaction Steps

Then, to a mixed solution of 8.65 g of 1-(4-biphenylyl)-7-t-butylpyrene, and 126 ml of tetrahydrofuran was added 4.1 g of N-bromosuccinimide under a nitrogen stream. This mixed solution was stirred at 30° C. for about 3 hours, and concentrated, 126 ml of methanol was added, and the mixture was stirred for about 1 hour, and filtered. To the resulting solid was added 30 ml of tetrahydrofuran, the mixture was heated and dissolved, 180 ml of methanol was added, and the mixture was stirred for about 1 hour, and filtered. After the resultant was purified by silica gel column chromatography, the solid obtained by evaporation was washed with 126 ml of methanol, and vacuum dried to obtain 8.8 g of 1-bromo-3-(4-biphenylyl)-7-t-butylpyrene.
