Procedure

Using Method C above, 1-ethynyl-1-cyclopentanol (35.8 mg, 0.33 mmol) (Aldrich) was coupled with (Z)-1,3-dihydro-5-fluoro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (50 mg, 0.13 mmol) (Starting Material 6) using (Ph3P)4Pd (15 mg) and Cul (2.5 mg) as catalyst in DMF (4 mL) and Et3N (4 mL) as solvent at 80 IC for 5 h to yield (Z)-1,3-Dihydro-5-fluoro-4-[(1-hydroxy-cyclopentyl)ethynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 32 mg, 67%).
