실험 절차

Using Method C above, propargyl alcohol (0.11 g, 1.95 mmol) (Aldrich) was coupled with (Z)-1,3-dihydro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-5-nitro-2H-indol-2-one (0.32 g, 0.78 mmol) (Starting Material 2 above) using (Ph3P)2PdCl2 (27.4 mg) and CuI (7.4 mg) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 85° C. for 18 h to yield (Z)-1,3-dihydro-4-(3-hydroxy-1-propynyl)-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-5-nitro-2H-indol-2-one. (Yield 0.12 g, 46%).
