Pd(PPh3)4 (231 mg, 0.2 mmol) was then added and the reaction mixture was then heated at 90 C. for 24 hours under a vigorous stirring and a N2 atmosphere. The solvent was removed in vacuo and the residue was then suspended in water (50 ml) and extracted with ethyl acetate (3*50 ml). The organics were combined, washed with saturated brine and dried over sodium sulphate. The solvent was removed in vacuo and the residue was purified by column chromatography (silica; ethyl acetate:ethanol; 9:1) to give the title compound as a white solid (620 mg, 41%). 1H-NMR (300 MHz, DMSO-d6): δ=3.38 (4H, t, J 5 Hz); 3.71 (4H, t, J 5 Hz); 5.49 (1H, d, J 2 Hz); 6.49 (1H, d, J 2 Hz); 7.06 (1H, dd, J 1 and 8 Hz); 7.26 (4H, m); 7.46 (1H, dd, J 1.5 and 8 Hz); 7.55 (1H, dd, J 1.5 and 8 Hz). m/z (LC-MS, ESP): 380 (M++1). |
