More tetrakis-triphenylphosphine-palladium-(0) (50 mg) is added and the mixture is stirred for another 5 h at 100 C. After cooling to room temperature the mixture is diluted with ethyl acetate and aqueous NH4Cl solution. The aqueous phase is extracted with ethyl acetate and the combined extracts are washed with brine, dried over MgSO4 and concentrated in vacuo. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 100:0?90:10) to give the title compound. LC (method 7): tR=1.22 min; Mass spectrum (EI+): m/z=250 [M]+.
