Reaction Steps
Using Method C above, rac-3-hydroxy-3-ethynyl-pyrrolidine (35.1 mg, 0.32 mmol) (Example 97C) was coupled with (Z)-3-[(4-acetyl-1H-pyrrol-2-yl)methylene]-1,3-dihydro-5-fluoro-4-iodo-2H-indol-2-one (50 mg, 0.13 mmol) (see Example 90B) using (Ph3P)4Pd (15 mg) and CuI (3.0 mg) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 85° C. for 5 h. (Yield 10 mg, 21%).
