Reaction Steps

The obtained 3,6-bis(5-methylthiophen-2-yl)carbazole (8.07 g, 22.4 mmol), 4-iodoanisole (21.00 g, 89.7 mmol), copper powder (0.71 g) and potassium carbonate (12.40 g) were mixed together. The mixture was refluxed in a nitrogen atmosphere for 6 hours and cooled to 100° C. Next, toluene (80 mL) was added thereto, and the resultant mixture was filtrated using a filtration aid to remove insoluble matter. Thereafter, the solvent was evaporated under reduced pressure. The residue was dissolved in methylene chloride, and the solution was washed with water and dried to obtain a brown liquid. Next, the obtained liquid was purified through silica gel column chromatography using as an eluent a solvent mixture of methylene chloride/hexane (3/7 by volume), to thereby obtain 4.39 g of 3,6-bis(5-methylthiophen-2-yl)-9-(4-methoxyphenyl)carbazole.
