Reaction Steps

Using Method C above, N-propargylacetamide (32.8 mg, 0.34 mmol) (prepared by the reaction of propargylamine (Aldrich) with acetyl chloride and triethylamine in dichloromethane at 0° C. for 3 h) 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 5 h to give N-[3-[2,3-dihydro-5-fluoro-3-[(5-methyl-3H-imidazol-4-yl)methylene]-2-oxo-1H-indol-4-yl]-prop-2-ynyl]-acetamide. (Yield 35 mg, 77%).
