실험 절차

The 3-bromo-6-phenyl-N-(4-methylphenyl)carbazole (3.20 g) and 4-methoxyphenylboronic acid (1.65 g) were added to a solvent mixture of toluene (30 mL) and ethanol (8 mL), followed by bubbling with nitrogen. Then, tetrakistriphenylphosphine palladium (150 mg) and 21.2% aqueous sodium carbonate solution (7.80 g) were added to the mixture, and the resultant mixture was refluxed under nitrogen flow for 3 hours. The mixture was diluted with toluene. The toluene layer was washed with water and dried and the toluene was evaporated. The residue was treated through silica gel column chromatography (eluent: toluene), to thereby obtain 2.30 g of 3-phenyl-6-(4-methoxyphenyl)-N-(4-methylphenyl)carbazole as colorless powder.
