実験手順

Using Method S above, phenyl boronic acid (75.2 mg, 0.617 mmol) (Aldrich) was coupled with (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-5-nitro-2H-indol-2-one (150 mg, 0.41 mmol) (Starting Material 6) using DPPFPdCl2 (17 mg) (Aldrich) as catalyst in aqueous 2M Na2CO3 (0.42 mL, 0.84 mmol) and DME (15 mL) at reflux for 18 h to give (Z)-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-5-nitro-4-phenyl-2H-indol-2-one (yield: 120 mg, 80%).

後処理
