Aniline → 9,9-Dibutyl-n-(9,9-dibutylfluorenyl)-n-phenylfluorenamine

Participants

Reaction Steps

40 parts of 9,9-dibutyl-2-iodofluorene, 3.7 parts of aniline, 30 parts of potassium carbonate, 6 parts of copper powders (200 meshes), and 0.87 parts of 18-crown-6 were dissolved in 50 parts of dimethylformamide (DMF), and the obtained solution was reacted in a nitrogen atmosphere at 160° C. for 24 hours. After completion of the reaction, the reaction product was filtrated, and the filtrate was then extracted with ethyl acetate-water. The ethyl acetate phase was dried over magnesium sulfate, and the ethyl acetate was then distilled away, thereby obtaining a brown tarry substance. This brown tarry substance was separated and purified by column chromatography (hexane-ethyl acetate) to obtain 15 parts of 9,9-dibutyl-N-(9,9-dibutylfluorenyl)-N-phenylfluorenamine (the following Compound (344)) in the form of a colorless crystal.
