72% | With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In tetrahydrofuran; water; at 80℃; | General procedure: 2,7-dibromonaphthalene (40.0 g, 139.9 mmol), the starting material, placed in a round bottom flask, dissolved in 700 mL of THF, (2-nitrophenyl) boronic acid (51.4 g, 307.7 mmol), Pd(PPh3)4 (4.9 g, 4.2 mmol), K2CO3 (58.0 g, 419.6 mmol),300 mL of water was added and stirred at 80 C . After the reaction was completed, the reaction mixture was extracted with CH2Cl2 and water. The organic layer was dried over MgSO 4 and concentrated. The resulting compound was purified by silicagel column and recrystallized to obtain 42.2 g (yield: 84%) of the product. |
