実験手順
A solution of Intermediate 1 (250 mg) obtained in Example 1, Step A, 2,6-di(tert-butyl)-4-methylphenol (0.5 mg, Tokyo Kasei Kogyo), and tri(n-butyl)vinyltin (0.25 ml, Tokyo Kasei Kogyo) in toluene (8 ml) is added with tetrakis(triphenylphosphine)palladium(0) (13 mg, Kanto Chemicals) under a nitrogen gas atmosphere, and the mixture is refluxed by heating for 12 hours. The reaction mixture is cooled to room temperature, and then the solvent is evaporated under reduced pressure. The residue is purified by silica gel chromatography (n-hexane:ethyl acetate=2:1) to obtain the title compound (195 mg (predictive yield)).
