Procedure
Using Method C above, 5-hexynamide (46 mg, 0.4 mmol) (prepared from 5-hexynoic acid by Method G above) was coupled with (Z)-1,3-dihydro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (Starting Material 2 supra) (113 mg, 0.31 mmol) using (Ph3P)2PdCl2 (12 mg) and Cul (6 mg) as catalyst in DMF (1 mL) and Et3N (1 mL) as solvent at 70° C. for 22 h yielding (Z)-6-[2,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2-oxo-1H-indol-4-yl]-5-hexynamide. (Yield 52 mg, 48%).
