Reaction Conditions

Reaction Steps

A mixed solution of 5 g of 1,6-dibromopyrene, 2.1 g of benzothiazole, 5 g of cesium carbonate, 0.31 g of cuprous iodide, 0.12 g of triphenylphosphine, 57 mg of palladium acetate and 50 ml of dimethylformamide was heated while stirred under nitrogen gas stream at a temperature of 130° C. for 6 hours. The mixed solution was cooled to room temperature, thereafter filtered and washed with 10 ml of dimethylformamide and 100 ml of dichloromethane. The filtrate was washed twice with 50 ml of water, dried by magnesium sulfate and thereafter evaporated. The filtrate was purified by silica gel column chromatography and vacuum dried to thereafter obtain 1.1 g of 6-bromo-1-(benzothiazole-2-yl)pyrene.
