Procedure

Using Method C above, N-methylpropargyl amine (43.6 mg, 0.66 mmol) was coupled with (Z)-3-[(4-acetyl-1H-pyrrol-2-yl)methylene]-1,3-dihydro-5-fluoro-4-iodo-2H-indol-2-one (100 mg, 0.25 mmol) (Example 90B) using (Ph3P)4Pd (30.1 mg) and Cul (6.0 mg) as catalyst in DMF (6 mL) and Et3N (6 mL) as solvent at 89° C. for 5 h to yield (Z)-3-[(4-Acetyl-1H-pyrrol-2-yl)methylene]-1,3-dihydro-5-fluoro-4-[3-(N-methylamino)-1-propynyl]-2H-indol-2-one. (Yield 10 mg, 12%).
