Next, a mixed solution of 7.63 g of 7-t-butyl-1-(4-methylphenyl)pyrene, 105 ml of dichloromethane and 35 ml of methanol was cooled to 0° C. under an argon gas stream and then 8.54 g of benzyltrimethylammonium tribromide was added over 5 minutes. This mixed solution was stirred at room temperature for 4 hours and 0.85 g of benzyltrimethylammonium tribromide was added, followed by stirring for 1.5 hours. To the reaction solution, 40 ml of water was poured, followed by extraction twice with 80 ml of dichloromethane. The combined organic layer was washed with 50 ml of water, dried over magnesium sulfate and then evaporated. To the resulting solid, 25 ml of methanol was added, and then the resulting solution was stirred for one hour, filtered and vacuum-dried to obtain 8.91 g of 1-bromo-7-t-butyl-3-(4-methylphenyl)pyrene.
