Procedure
Under an argon atmosphere, Intermediate 147(d) of Example 147 (0.250 g, 0.661 mmol), tributyl-vinyl-tin (0.420 g, 1.32 mmol) and tetrakis(triphenylphosphine)palladium(0) (38 mg, 0.033 mmol) in anhydrous N,N-dimethylformamide (5 mL) were heated at 85° C. for 16 hours. The reaction was filtered through a thin pack of diatomaceous earth, and the filtrate concentrated in vacuo. Silica gel chromatography (eluted with 1:4 ethyl acetate: dichloromethane) afforded the title compound (0.18 g, 0.552 mmol) as a yellow powder in 84% yield.
