Participants

Reaction Conditions

Reaction Steps

Next, 25.0 g (0.10 mol) of tert-butylpyrene and 250 ml of DME (1,2-dimethoxyethane) were charged in a reaction vessel, and the mixture was cooled to 0° C. Next, NBS was added in an amount of 4 equivalents relative to tert-butylpyrene, and the resulting mixture was stirred overnight at room temperature, filtered, and recrystallized to produce 29.5 g of bromo-tert-butylpyrene crystals in a yield of 90%.
