実験手順

A solution of 1-acetoxy-4-dibenzylamino-2-butene (3.0 g, 9.8 mmol) and 2,6-diphenylpiperidine (2.3 g, 9.8 mmol) in THF (25 ml) is treated with tetrakis(triphenylphosphine)palladium (0) (0.5 g, 0.45 mmol) and stirred at room temperature overnight. The reaction mixture is concentrated in vacuo. The residue is redissolved in THF (100 ml) and treated with 20% aqueous sodium hydroxide (25 ml). The mixture is stirred for one hour, concentrated, and extracted with diethyl ether. The ether extracts are dried and concentrated to give an orange oil which is purified by chromatography (silica gel; 5% ethyl acetate in hexanes) to give the title compound in a yield of 2.8 g (59%) as a clear oil. MS m/z 486 (M+)
