Procedure

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-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (150 mg, 0.64 mmol) (from Example 82) was coupled with 1-bromo-2-nitrobenzene (150 mg, 0.74 mmol) (Aldrich) using CuI (13 mg, 0.068 mmol) (Aldrich) and (Ph3P)2PdCl2 (22 mg, 0.031 mmol) (Aldrich) as catalyst in 2 mL DMF and 4 mL triethylamine at 70° C. for 15 hours to give (Z)-1,3-dihydro-5-(2-nitrophenyl)ethynyl-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one as a red powder. (Yield 115 mg, 51%).
