YieldReaction ConditionsOperation in experiment
65% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In tetrahydrofuran; water; at 80℃; for 12h;Inert atmosphere; In the nitrogen ambient, after 2 - (terphenyl-3-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolanes (20 g, 56 mmol) were melted in theTHF 250 ml here 3-bromo-3'-chlorobiphenyls (22.5 g, 84 mmol) and tetrakis(triphenylphosphine) palladium (Pd(PPh(sub)3(/sub))(sub)4(/sub)) (3.24 g, 2.8mmol) were put and it mixed. Saturated potassuim carbonate(K(sub)2(/sub)CO(sub)3(/sub)) (15.5 g, 112 mmol) were put in water and itheated up in 80 for 12 hours and it refluxed.After water was put in into the reaction solution after the reaction completion andit extracted in the dichloromethane (DCM) moisture was removed to the anhydrousMgSO4 it filtered and it was concentrated under reduced pressure. The residueobtained in this way was refined to the flash column chromatography afterdividing and intermediate I-7s (21 g, 65 %) were obtained.

YieldReaction ConditionsOperation in experiment
65% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In tetrahydrofuran; water; at 80℃; for 12h;Inert atmosphere; In the nitrogen ambient, after triphenylen-2-ylboronic acids (20 g, 73.5 mmol)were melted in the THF 300 ml here 3-bromo-3'-chlorobiphenyls (30 g, 110 mmol)and tetrakis (triphenylphosphine) palladium (Pd(PPh(sub)3(/sub))(sub)4(/sub))(4.25 g, 3.67 mmol) were put and it mixed. Saturated potassuim carbonate(K(sub)2(/sub)CO(sub)3(/sub)) (20.32 g, 138 mmol) were put in water and itheated up in 80 for 12 hours and it refluxed.After water was put in into the reaction solution after the reaction completionand it extracted in the dichloromethane (DCM) moisture was removed to theanhydrous MgSO4 it filtered and it was concentrated under reduced pressure.The residue obtained in this way was refined to the flash column chromatographyafter dividing and intermediate I-9s (20 g, 65 %) were obtained.
