Dimethylformamide → 1-Bromo-3,6,8-tri(4-methylphenyl)pyrene

Participants

Reaction Steps

Next, a mixed solution of 1.5 g of 1,3,6-tri(4-methylphenyl)pyrene, 0.68 g of N-bromosuccinimide and 30 ml of dimethylformamide was stirred under a nitrogen gas flow at 60° C. for 6 hours. After cooling to room temperature, 50 ml of water was injected, followed by extraction with 100 ml of dichloromethane. The organic layer was washed twice with 50 ml of water, dried over magnesium sulfate and then evaporated. The resultant concentrate was purified by silica gel column chromatography and then vacuum-dried to obtain 1.5 g of 1-bromo-3,6,8-tri(4-methylphenyl)pyrene as a pale yellow powder.
