Using Method C above, N-methylpropargylamine (44.9 mg, 0.65 mmol) was coupled with (Z)-1,3-dihydro-5-fluoro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (100 mg, 0.26 mmol) (Starting Matenal 6, 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 18 h to yield (Z)-1,3-Dihydro-5-fluoro-4-[3-(N-methylamino)-1-propynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 10 mg, 12%).
