Versuchsvorschrift

Ethynyl(trimethyl)silane (80 mg), PdCl2(PPh3)2 (29 mg), CuI (16 mg), and TEA (0.25 g) were added to a chloroform (5.0 mL) solution of N-[1-(4-iodophenyl)ethyl]cyclopropylamine (0.23 g) as obtained in Example 14-(1), and the mixture was stirred in a nitrogen atmosphere for 24 hours at room temperature. Further, stirring was continued for 2 hours at 45° C., and then PdCl2(PPh3)2 (29 mg) was added. After the system was refluxed in a nitrogen atmosphere for 5 hours, the reaction mixture was concentrated. The resulting residue was purified by OH type silica gel chromatography (hexane/ethyl acetate=85/15) to obtain N-(1-{4-[(trimethylsilyl)ethynyl]phenyl}ethyl)cyclopropylamine (brown oil) (0.14 g, 66%).
