実験手順

Using Method D above, 3-hydroxy-3-(4-hydroxyphenyl)-1-propyne (120 mg, 0.84 mmol) (from Example 17 above) was coupled to (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (110 mg, 0.34 mmol) (Starting Material 1) using (Ph3P)2PdCl2 (30 mg) (Aldrich) and CuI (15 mg) (Aldrich) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 70° C. for 16 h, yielding rac-(Z)-1,3-dihydro-4-[3-hydroxy-3-(4-hydroxyphenyl)-1-propynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 62 mg, 47%).
