Procedure

This compound was prepared in a manner analogous to the preparation of (Z)-1,3-dihydro-5-(4-hydroxyphenyl)ethynyl-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one in Example 83 above. In this example, (Z)-1,3-dihydro-5-ethynyl-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (90 mg, 0.38 mmol) (from Example 82) was coupled with iodobenzene (219 mg, 1.07 mmol) (Aldrich) using CuI (8 mg, 0.042 mmol) (Aldrich) and (Ph3P)2PdCl2 (14 mg, 0.020 mmol) (Aldrich) as catalyst in 1 mL DMF and 2 mL triethylamine at 70° C. for 15 hours to give (Z)-1,3-dihydro-5-phenylethynyl-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one as a yellow powder. (Yield 92 mg, 78%)
