Reaction Steps

Using Method C above, methyl propargyl ether (34 mg, 0.49 mmol) (Aldrich) was coupled with (Z)-1,3-dihydro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (150 mg, 0.41 mmol) (Starting Material 2 supra) using (Ph3P)2PdCl2 (20 mg) and CuI (10 mg) as catalyst in DMF (2 mL) and Et3N (2 mL) as solvent at 70° C. for 18 h to yield (Z)-1,3-dihydro-4-(3-methoxy-1-propynyl)-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 69 mg, 55%).
