Procedure

Using Method C above, 3-amino-3-methyl-1-butyne (42.2 mg, 0.51 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) (75 mg, 0.203 mmol) using (Ph3P)4Pd (23.5 mg) and Cul (4 mg) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 80° C. for 18 h to give (Z)-4-[3-amino-3-methyl-1-butynyl]-1,3-dihydro-5-fluoro-3-[(4-methyl-1H-imidazol-5-yl)methylene]-2H-indol-2-one. (Yield 44 mg, 67%).
