Reaction Steps
Using Method C above, 2-propynyl carbamic acid methyl ester (71.3 mg, 0.63 mmol) (see below) was coupled with (Z)-1,3-dihydro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (110 mg, 0.3 mmol) (Starting Material 2 supra) using (Ph3P)2PdCl2 (11 mg) and CuI (3 mg) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 80° C. for 6 h to give (Z)-[3-[2,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2-oxo-1H-indol-4-yl]-2-propynyl]carbamic acid methyl ester. (Yield 25 mg, 23%).
