Reaction Steps

60 mg (128 μmol) 4-[6-(4-ethyl-6-oxo-1,4,5,6-tetrahydro-pyridazin-3-yl)-benzoxazol-2-yl]-phenyl trifluoro-methanesulphonate, 14.7 μl (128 μmol) styrene, 2.9 mg (13 μmol) palladium-(II)-acetate, 4.1 mg (13 μmol) tri-o-tolylphosphine, 72 μl (513 μmol) triethylamine and 2 ml acetonitrile are combined and stirred overnight at 80° C. Then a further 7.5 μl styrene, 2.9 mg palladium-(II)-acetate and 4 mg tri-o-tolyphosphine are added and the mixture is stirred for 5 days at 80° C. Then it is diluted with DCM and extracted successively with 10% sodium carbonate solution and sat. saline solution. The org. phase is evaporated down completely i.V. and the residue is purified through silica gel (eluant: DCM/methanol). The residue obtained is crystallised from cyclohexane/EA.
