실험 절차

Using Method C above, 3,5-dimethyl-1-hexyn-3-ol (61 mg, 0.48 mmol) (Aldrich) was coupled with (Z)-1,3-dihydro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (Starting Material 2 supra) (146 mg, 0.4 mmol) using (Ph3P)2PdCl2 (20 mg) and Cul (10 mg) as catalyst in DMF (2 mL) and Et3N (2 mL) as solvent at 70° C. for 15 h to yield rac-(Z)-1,3-dihydro-4-(3,5-dimethyl-3-hydroxy-1-hexynyl)-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 87 mg, 60%).
