Reaction Steps

This compound was also prepared in a manner to analogous to the preparation of (Z)-I,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 (100 mg, 0.43 mmol) (from Example 82) was coupled with 3-iodophenol (110 mg, 0.50 mmol) (Aldrich) using CuI (8 mg, 0.042 mmol) (Aldrich) and (Ph3P)2PdCl2 (15 mg, 0.021 mmol) (Aldrich) as catalyst in 1 mL DMF and 3 mL triethylamine at 70° C. for 13 hours to give (Z)-1,3-dihydro-5-(3-hydroxyphenyl)ethynyl-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one as a yellow powder. (Yield 100 mg, 71%).
