Procedure
Using Method C above, 2-propynylurea (50 mg, 0.51 mmol) (see below) 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)-[3-[5-fluoro-2,3-dihydro-3-[(4-methyl-1H-imidazol-5-yl)methylene]-2-oxo-1H-indol-4-yl]-2-propynyl]urea. (Yield 11 mg, 16%).
