Procedure

This compound was prepared in a manner analogous to the preparation of (Z)-1,3-dihydro-3-[(1H-pyrrol-2-yl)methylene]-5-(trimethylsilyl)-ethynyl-2H-indol-2-one in Example 81 above. In this example, (Z)-5-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (740 mg, 2.32 mmol) (from Example 91) was coupled with (trimethylsilyl)acetylene (640 mg, 6.52 mmol) (Aldrich) using CuI (40 mg, 0.21 mmol) (Aldrich) and (Ph3P)2PdCl2 (90 mg, 0.13 mmol) (Aldrich) as catalyst in 10 mL DMF and 10 mL triethylamine at 70° C. for 22 hours to give (Z)-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-5-(trimethylsilyl)ethynyl-2H-indol-2-one. (Yield 410 mg, 52%).
