반응 단계
Using Method D above, trimethylsilyl acetylene (0.94 g, 9.63 mmol) (Aldrich) was coupled with (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (2.05 g, 6.42 mmol) (Starting Material 1 supra) using (Ph3P)2PdCl2 (0.23 g) and Cul (61 mg) as catalyst in DMF (15 mL) and Et3N (15 mL) as solvent at 80° C. for 2 days to give (Z)-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-4-(2-trimethylsilyl-ethynyl)-2H-indol-2-one. (Yield 1.3 g, 60%).
