YieldReaction ConditionsOperation in experiment
With Aliquat 336;tetrakis(triphenylphosphine) palladium(0); calcium carbonate; In water; toluene; at 130℃; for 4h; Preparation of Compound (116)A reaction vessel was charged with Compound (113) (4.2 g, 30.0 mmol) and the ester compound (Compound 115) (4.7 g, 10.0 mmol), and tetrakispalladiumtriphenylphosphine (Pd(PPh3)4) (1.2 g, 1.0 mmol) was added thereto. The mixture was dissolved in toluene (80 mL). To the solution, added were Aliquat 336 (0.5 g, 1.0 mmol) and aqueous 2M calcium carbonate solution (24 mL). The resultant mixture was stirred at 130 C. under reflux for 4 hours. To the precipitate formed, methanol (200 mL) was poured to form solid, which was then dissolved in chloroform (300 mL). After filtration, the organic layer was evaporated under reduced pressure. Recrystallization from tetrahydrofuran (30 mL) gave the target compound (116) (TPN-1) (2.2 g, overall yield: 38%).1H NMR (200 MHz, CDCl3) δ=7.22-7.32 (m, 8H), 7.48-7.54 (m. 5H), 7.67-7.89 (t, 8H), 8.10-8.12 (m, 3H), 8.34 (d, 1H), 8.93-8.99 (m, 3H)MS/FAB: 556.22 (found), 556.69 (calculated)

YieldReaction ConditionsOperation in experiment
62.33% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In ethanol; water; toluene; at 80℃; for 16h; 2-Bromo-9,10-diphenylanthracene (32.76 g, 80 mmol),4- (1-phenyl-1H-benzimidazol-2-yl) benzene acid (4- (. 1-Phenyl-IH-benzimidazol-2-yL)phenylboronic acid) (26.48 g, 88mmol), potassium carbonate (27.64g, 200mmol) and Pd (PPh3. 3). 4(4.64 g) putinto the reaction The flask was further charged with 597 ml of toluene, 97 ml of ethanol and 194 ml of deionized water, stirred and refluxed at 80 C for16 hours.After the reaction was cooled to room temperature, the water layer was removed and concentrated to sticky after adding silica gel 80g, then add tetrahydrofuran,through a silica gel column, rinse the product with toluene, the filtrate was concentrated to a viscous After pouring into a beaker static analysis, filtrationCompound A4 (30 g, 62.33% yield) was obtained asa solid which wasdried in 30 g of a gray solid
