Procedure
A mixture of Intermediate A (3.52 g, 10 mmol), 9,9-dihexylfluorene-2,7-diboronic acid (1.90 g, 4.5 mmol), sodium carbonate (2.12 g, 20 mmol) in water (10 mL), tetrakis(triphenylphosphine)palladium (0) (1.00 g, 0.86 mmol), n-butanol (80 mL), and toluene (20 mL) was stirred and heated under argon at 110° C. After 48 hours, 1-bromo-4-butylbenzene (3.0 mL, 17 mmol) was added followed by sodium carbonate (2.12 g, 20 mmol) in water (10 mL) and tetrakis(triphenylphosphine)palladium (0) (1.00 g, 0.86 mmol), and heating was continued for an additional 20 hours. The reaction mixture was poured into water (200 mL and extracted with ethyl acetate). The extract was dried over anhydrous sodium sulfate, the volatiles were removed under reduced pressure, and the residue was chromatographed (silica gel, dichloromethane/ethyl acetate 3:1). The first fraction gave Intermediate E (414 mg, 10%).
