Procedure

Using Method C above, 1-pentyn-3-ol (58.9 mg, 0.7 mmol) (Aldrich) was coupled with (Z)-1,3-dihydro-5-fluoro-4-iodo-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (100 mg, 0.28 mmol) (Starting Material 5, supra) using (Ph3P)4Pd (32 mg) and CuI (5.3 mg) as catalyst in DMF (5 mL) and Et3N (5 mL) as solvent at 85° C. for 10 h to yield rac-(Z)-1,3-Dihydro-5-fluoro-4-(3-hydroxy-1-pentynyl)-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 64 mg, 70%).
