実験手順

A solution of (Z)-1,3-dihydro-4-iodo-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (39 mg, 0.116 mmol) (from Example 71 above), triethylamine (65 μL, 0.464 mmol), tri-o-tolylphosphine (7 mg, 0.023 mmol) (Aldrich), palladium(ll) acetate (2 mg, 0.009 mmol) (Aldrich), and 2-chlorostyrene (24 mg, 0.173 mmol) (Aldrich) in 3 mL of dry N,N-dimethylformamide was heated at 85° C. under a nitrogen atmosphere for 20 h. The reaction mixture was allowed to cool to room temperature and then directly purified by flash chromatography (Merck Silica gel 60, 230-400 mesh, 5% ethyl acetate-benzene elution) to yield pure 4-[(E)-2-(2-chlorophenyl)-ethenyl]-1,3-dihydro-(Z)-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one as a yellow solid. (Yield 27 mg, 67%; mp=257-258° C.).
