实验步骤: 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 CuI (2.5 mg) as catalyst in DMF (4 mL) and Et3N (4 mL) as solvent at 80° C. 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%).

实验步骤: Using Method D above, 1-ethynyl-cyclopentanol (86.3 mg, 0.78 mmol) (Aldrich) was coupled with (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (0.1 g, 0.31 mmol) (Starting Material 1 above) using DPPFPdCl2 (12.6 mg) and CuI (3 mg) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 85° C. for 2 days to yield (Z)-1,3-dihydro-4-[(1-hydroxycyclopentyl)ethynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 43 mg, 40%).
