57% | With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In tetrahydrofuran; water; for 12h;Inert atmosphere; Reflux; | To a flask was added 3,5-dibromobenzonitrile (3 g, 11.6 mmol), 4-(1-naphthyl)-benzenesulfonic acid (2.9 g, 11.6 mmol), potassium carbonate (4.1 g, 30 mmol)tetraphenyllphosphine palladium (0.1 g),tetrahydrofuran (30 mL) and water (15 mL)heated to reflux under nitrogen for 12 hours, cooled, extracted with dichloromethane, dried and concentrated. The crude product was purified by column chromatography to give 2.5 g of product in 57% yield. |
