Reaction Steps

Compound 5 (see WO 2007046658 A1, US 20070205412 A1 and WO 2007086695 A1, which are incorporated by reference herein for their relevant teachings) was prepared as follows: a mixture of Compound 2 (5.270 g, 13.30 mmol), 9,10-dibromoanthracene (13.41 g, 39.90 mmol), tetrakis(triphenylphosphine)palladium(0) (0.922 g, 0.798 mmol), Na2CO3 (9.539 g, 90.00 mmol), H2O (90 mL) and tetrahydrofuran (THF) (150 mL) was degassed with argon for 1.5 h. while stirring. The reaction mixture was then maintained under argon at 85° C. while stirring for 46 h. Upon completion, the reaction was cooled to RT and poured over dichloromethane (about 500 mL). The soluble organics were then washed with H2O and brine, dried over MgSO4, filter and concentrated in vacuo. The crude product was purified via flash chromatography (SiO2, 100% dichloromethane) to provide Compound 5 (5.25 g, 75%) as a light yellow solid.
