N-methylpropyn-2-ylamine → (Z)-1,3-Dihydro-5-fluoro-4-[3-(N-methylamino)-1-propynyl]-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one

Participants

Reaction Steps

Using Method C above, N-methylpropargyl amine (48.4 mg, 0.7 mmol) was coupled with (Z)-1,3-dihydro-5-fluoro-4-iodo-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (100 mg, 0.28 mmol) (Starting Material 5, supra) using (Ph3P)4Pd (32 mg) and Cul (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-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 10 mg, 12%).
