Reaktionsschritte

A mixture of 2′-benzyloxy-biphenyl-2-boronic acid (100 mg, 0.33 mmol), 4-bromo-N-(1-phenyl-methanoyl)-benzenesulfonamide (95 mg, 0.28 mmol), potassium carbonate (309 mg, 2.24 mmol), and tetrakis(triphenylphosphine)palladium(0) (38 mg, 0.033 mmol) in 1:1 toluene/ethanol (5 ml) was stirred and heated at 90° C. under nitrogen for 16 hours. After cooling the mixture was diluted with ethyl acetate and water. The organic phase was dried and evaporated. The residue was chromatographed eluting with ethyl acetate/iso-hexane (1:4-1:1) to give the title compound as a colourless solid. (40 mg 23%).
