Reaction Steps

To a 250 mL rbf was added cesium carbonate (4.93 g, 15.14 mmol) and anhydrous acetonitrile (50 mL). A solution of 4-(bis(4-chlorophenyl)amino)phenol (69, 2.5 g, 7.57 mmol) in acetonitrile (25 mL) was added, and an immediate light purple colour was observed. 1,2-dibromoethane (7.11 g, 37.9 mmol) was added and the reaction was heated to reflux for 5 days. After cooling to RT, the reaction mixture was poured into water (250 mL), mixed well and separated. The aqueous portion was extracted with EtOAc (2×100 mL) and the combined organics were washed with water (2×250 mL), dried over MgSO4, filtered and solvent removed by rotary evaporation. Flash chromatography (2% EtOAc/hexanes) afforded 70 as a clear, colourless oil (1.42 g, 43%).
