Versuchsvorschrift

Using Method D above, 3-hydroxy-3-(3-methoxyphenyl)-1-propyne (151 mg, 1.0 mmol) (prepared by the addition of ethynylmagnesium chloride (Aldrich) to 3-methoxybenzaldehyde (Aldrich) according to Method A above) was coupled to (Z)-4-bromo-1,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (Starting Material 1) (220 mg, 0.69 mmol) using (Ph3P)2PdCl2 (100 mg) (Aldrich) and CuI (55 mg) (Aldrich) as catalyst in DMF (5 mL) and Et3N (5 mL) as solvent at 70° C. for 18 h, yielding rac-(Z)-1,3-dihydro-4-[3-hydroxy-3-(3-methoxyphenyl)-1-propynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 66 mg, 24%).
