Under rigorous exclusion of oxygen a mixture of 200 mg (0.88 mmol) 2-chloro-6-methyl-isonicotinic acid tert-butyl ester, 10 mg palladium(II)acetate (0.044 mmol), 27 mg (0.44 mol) BINAP (R(+)-2,2-bis(diphenylphosphino)-1,1-binaphtalene) and 62 mg (0.88 mmol) but-3-enylamine in 10 ml toluene is heated at 60° C. for 4 h. The mixture is diluted with EtOAc, washed with 10% aqueous NaHCO3 and water, dried with sodium sulfate and evaporated. Chromatography of the product on silica gel (hexane/EtOAc 9:1) yields the title compound.
