Reaction Steps
Using Method C above, N,N-diethyl propargylamine (38 mg, 0.34 mmol) (Aldrich) was coupled with (Z)-1,3-dihydro-5-fluoro-4-iodo-3-[(4-methyl-1H-imidazol-5-yl)methylene]-2H-indol-2-one (Starting Material 3 supra) (50 mg, 0.135 mmol) using (Ph3P)4Pd (16 mg) and CuI (3 mg) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 80° C. for 18 h to give (Z)-4-(3-(N,N-diethylamino)-1-propynyl]-1,3-dihydro-5-fluoro-3-[(4-methyl-1H-imidazol-5-yl)methylene]-2H-indol-2-one. (Yield 20 mg, 42%).
