Reaction Steps

In accordance with Method S above, 4-hydroxy-phenyl boronic acid (96.6 mg, 0.70 mmol) (see Gilman, supra) was coupled with (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (150 mg, 0.47 mmol) (Starting Material 7) using (Ph3P)4Pd (27 mg) (Aldrich) as catalyst in aqueous 2M Na2CO3 (0.47 mL, 0.94 mmol) and DME (10 mL) at reflux for 2 days to give (Z)-1,3-dihydro-4-(4-hydroxyphenyl)-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (yield: 60 mg, 73%, based on 70 mg recovered starting oxindole).
