Procedure

Using Method C above, 2-phenyl-3-butyn-2-ol (70 mg, 0.48 mmol) (Aldrich) 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 15 h, yielding rac-(Z)-1,3-dihydro-4-[3-hydroxy-3-phenyl-1-butynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 85 mg, 55%).
