Reaction Steps
Using Method D above, 3-hydroxy-3-(3-hydroxy-4-methoxyphenyl)-1-propyne (105 mg, 0.59 mmol) (from Example 34 above) was coupled to (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (122 mg, 0.38 mmol) (Starting Material 1) using (Ph3P)2PdCl2 (34 mg) (Aldrich) and CuI (15 mg) (Aldrich) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 70° C. for 18 h, yielding rac-(Z)-1,3-dihydro-4-[3-hydroxy-3-(3-hydroxy-4-methoxyphenyl)-1-propynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 101 mg, 64%).
