YieldReaction ConditionsOperation in experiment
77% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In tetrahydrofuran; water; at 65℃; for 3h;Inert atmosphere; Compound 4 (2.5 g, 7.0 mmol), Pd(PPh3)4 (0.45 g, 0.35mmol) were added to 100 mL of dry THF solution, then 1,4-dibromobenzene (9.6 g, 15 mmol) and 2 M K2CO3 solution(7 mL), which was dissolved in H2O, was added to the reaction mixture. The reaction mixture was heated to 65 Cfor 3h under nitrogen. After the reaction was finished, extracted with diethyl ether and water. The organic layer was dried with anhydrous MgSO4 and filterd. The solvent was evaporated. The product was isolated by silica gel column chromatography using CHCl3:hexane (1:10) eluent to afford a white solid (Yield 77%). 1H NMR (300 MHz, CDCl3) δ7.80 (s, 1H), 7.74 (s, 2H), 7.69 (d, 4H), 7.58 (m, 4H), 7.48 (t,4H), 7.39 (t, 2H).

Then, 2M K2CO3 solution (20 mL), whichwas dissolved in H2O, was added to the reaction mixture. The reactionmixture was heated to 65 C for 12 h under nitrogen. After the reactionwas finished, the reaction mixture was extracted with CHCl3 and water.The organic layer was dried with anhydrous MgSO4 and filtered. Thesolvent was evaporated. The product was isolated by silica gel columnchromatography using CHCl3: n-hexane (1: 10) eluent to afford a whitesolid (2.07 g, Yield 77%). 1H NMR (300 MHz, CDCl3): δ = 7.80 (s, 1H),7.74 (s, 2H), 7.69 (d, 4H), 7.58 (m, 4H), 7.48 (t, 4H), 7.39 (t, 2H);EI + -Mass: 384.

YieldReaction ConditionsOperation in experiment
87% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In tetrahydrofuran; at 80℃; for 8h;Inert atmosphere; Nitrogen environment in the compound I-8 (95 g, 267 mmol) and tetrahydrofuran (THF) and then dissolved in 0.9L, where the 1-bromo-4-iodobenzene (83.0 g, 293 mmol) and tetrakis (triphenylphosphine) palladium (3.09 g and stirred into a 2.67 mmol). Into the potassuim carbonate (92.3 g, 668 mmol) in saturated water it was heated to reflux at 80 for 8 hours. After the reaction was completed, the reaction solution into water and extracted with dichloromethane (DCM) and then water was removed with anhydrous MgSO4, filter and was concentrated under reduced pressure. The obtained residue was purified by flash column chromatography to give the compound I-9 (89.5 g, 87%).
