The reaction mixture was cooled to room temperature and extracted with ethyl acetate and dried with washed with brine MgSO4 The solvent was removed by separation and purification by column chromatography (ethyl acetate / hexane = 1/2) of the solid of the title compound as a beige It was obtained (45percent, 1.07 g)Nitrogen gas in 50 mL 2-necked flask, the 4, 4'-dimethoxydiphenylamine (2.00 g, 8.72 mmol), 2, 2', 7, 7'-tetrabromo-9, 9'-spirobi[9H-fluorene] (1.23 g, 1.94 mmol), sodium tertbutoxide (1.12 g, 11.6 mmol), tris (dibenzylideneacetone) dipalladium (0) (0.071 g, 0.078 mmol) and tri-tert-butylphosphine (0.025 g, 0.12 mmol) to put this in dry toluene 15mL was added to 110 °C and stirred for 12 hours.
