Reaction Steps

A mixture of Compound 2 (3.00 g, 7.57 mmol), 2,2′-dibromo-1,1′-biphenyl (4.72 g, 15.1 mmol), tetrakis(triphenylphosphine)palladium(0) (0.350 g, 0.303 mmol), Na2CO3 (3.18 g, 30.0 mmol), H2O (30 mL) and tetrahydrofuran (THF) (50 mL) was degassed with argon for about 44 min while stirring. The reaction mixture was then maintained under argon at about 80° C. while stirring. Upon confirming consumption of the starting material by TLC (SiO2, 19:1-CH2Cl2:acetone), the reaction was cooled to RT and poured over CH2Cl2 (ca. 250 mL). The organics were then washed with H2O and brine, dried over MgSO4, filtered and concentrated in vacuo. The crude product was purified via flash chromatography (SiO2, 100% CH2Cl2 to 39:1-CH2Cl2:acetone) to yield Compound 3 (2.34 g, 62%) as an off-white foam: confirmed by LCMS (APCI): calculated for C31H21BrN2 (M+): 501; Found: 501.
