	With sodium carbonate;dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; In 1,4-dioxane; at 95 - 100℃; for 16 - 24h;	(+/-)-5,7-Difluoro-l,2,3,4-tetrahydro-3beta-hydroxy-6-(indol-7-yl)-2,2,4alpha- trimethylquinoline was prepared from (+/-)-6-bromo-5,7-difluoro-l,2,3,4-tetrahydro-3beta- hydroxy-2,2,4alpha-tetramethylquinoline and 7-(4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2- yl)indole using General Method 4. General Method 4: Palladium-catalyzed Suzuki cross-coupling of an aryl halide and an aryl boronic acid or aryl pinacol boronate. In a Schlenck reaction flask, a mixture of an aryl bromide (1 equiv); an aryl boronic acid or aryl pinacol boronate (1.0-1.3 equiv); and [l,r-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (3-10 mol %) is placed under vacuum, and back-filled with nitrogen. Dioxane (0.1-0.2 M) and 2M sodium carbonate (2 equiv) are introduced sequentially. The mixture is heated (95-100 0C) for 16-24 h. The mixture is partitioned between saturated ammonium chloride and EtOAc, resulting in a first organic layer and an aqueous layer. The first organic layer is collected and the aqueous layer is extracted with EtOAc. The organic layer from that extraction is combined with the first collected organic layer and that combined organic layer is washed with brine, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. Flash chromatography (silica gel, EtOAc/hexanes or other specified solvent), preparative thin-layer chromatography (prep TLC, EtOAc/hexanes or other specified solvents), preparative HPLC and/or recrystallization affords the desired compound.
