반응 단계

The obtained 9-(3-bromophenyl)-3,6-diphenylcarbazole (3.20 g, 6.75 mmol), 3-methoxyphenylboronic acid (1.54 g, 10.1 mmol) and tetrakis(triphenylphosphine)palladium (0.124 g) were added to a solvent mixture of toluene (30 mL) and ethanol (10 mL). Then, an aqueous solution of sodium carbonate (37.3 g) in distilled water (90 mL) was added the mixture. The resultant mixture was refluxed for 9 hours in a nitrogen atmosphere and then cooled to room temperature. The obtained mixture was diluted with methylene chloride and the insoluble matter was removed through filtration. The organic layer was washed with water and separated. The solvent was evaporated under reduced pressure. The residue was purified through silica gel column chromatography using as an eluent a solvent mixture of methylene chloride/hexane (2/3 by volume), to thereby obtain 2.89 g of [3′-(3,6-diphenylcarbazol-9-yl)biphenyl-3-yloxy]methane.
