Procedure

Using Method C above, N-methyl propargyl amine (23.3 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 (50 mg, 0.135 mmol) (Starting Material 3 supra) using (Ph3P)4Pd (15.6 mg) and Cul (3 mg) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 80° C. for 8 h to give (Z)-1,3-dihydro-5-fluoro-4-[3-(N-methylamino)-1-propynyl]-3-[(4-methyl-1H-imidazol-5-yl)methylene]-2H-indol-2-one. (Yield 17 mg, 41%).
