Procedure

Using Method C above, phenyl propargyl ether (65 mg, 0.49 mmol) (Lancaster) was coupled to (Z)-1,3-dihydro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (146 mg, 0.4 mmol) (Starting Material 2) using (Ph3P)2PdCl2 (20 mg) (Aldrich) and CuI (10 mg) (Aldrich) as catalyst in DMF (2 mL) and Et3N (2 mL) as solvent at 70° C. for 18 h, yielding (Z)-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-4-(3-phenoxy-1-propynyl)-2H-indol-2-one. (Yield 92 mg, 62%).
