Reaction Steps
Using Method D above, 3-hydroxy-3-(1H-pyrrol-2-yl)-1-propyne (212 mg, 1.75 mmol) (from Example 30 above) was coupled to (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (125 mg, 0.39 mmol) (Starting Material 1) using (Ph3P)2PdCl2 (42 mg) (Aldrich) and CuI (20 mg) (Aldrich) as catalyst in DMF (4 mL) and Et3N (4 mL) as solvent at 70° C. for 18 h, yielding rac-(Z)-1,3-dihydro-4-[3-hydroxy-3-(1H-pyrrol-2-yl)-1-propynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 68 mg, 49%).
