This compound was also 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-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (75 mg, 0.28 mmol) (from Example 93) was coupled with 4-iodophenol (75 mg, 0.34 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 1 mL triethylamine at 70° C. for 14 hours to give (Z)-1,3-dihydro-5-(4-hydroxyphenyl) ethynyl-3-[(3-methoxy-1H-pyrrol-2-yl)-methylene]-2H-indol-2-one as a yellow powder. (Yield 62 mg, 62%).
