実験手順

A solution of Intermediate 121 (500 mg), tri(n-butyl)vinyltin (518 μl, Tokyo Kasei Kogyo), tetrakis(triphenylphosphine)palladium(0) (28.1 mg) and 2,6-di-tert-butyl-p-cresol (3.2 mg, Tokyo Kasei Kogyo) in toluene (10 ml) was stirred at 110° C. for 3 hours. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=2:1) to obtain the title compound (409.5 mg).
