実験手順

Adding 0.66% by weight toluene solution in an amount of 100 microliter prepared by dissolving tri-t-butylphosphine into a mixed solution prepared by dissolving 4.50 g of 4-bromo-4′-(N-1-naphthyl-N-phenylamino)biphenyl, 1.11 g of aniline, 183 milligram of tris(dibenzylideneacetone)dipalladium(O) and 1.35 g of t-butoxysodium into toluene in an amount of 100 milliliter, the resultant solution was stirred at a room temperature for 5 hours. After the completion of the reaction, the solution was filtered with a use of celite and the filtrate was extracted with toluene. Concentrating the filtrate under a reduced pressure, the resultant crude product was refined by means of a column and as a result, 3.50 g of pale yellow powder was obtained
