반응 단계
Using Method D above, methyl 5-hexynoate (109 mg, 0.87 mmol) (see below) was coupled with (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (179 mg, 0.62 mmol) (Starting Material 1 supra) using (Ph3P)2PdCl2 (30 mg) and Cul (15 mg) as catalyst in DMF (4 mL) and Et3N (4 mL) as solvent at 70° C. for 15 h to yield (Z)-6-[2,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2-oxo-1H-indol-4-yl]-5-hexynoic acid methyl ester. (Yield 78 mg, 35%).
