Reaction Steps

Using Method D above, 3-hydroxy-3-(3-hydroxyphenyl)-1-propyne (140 mg, 0.94 mmol) (prepared by the addition of ethynylmagnesium chloride (Aldrich) to 3-hydroxybenzaldehyde (Aldrich) through Method B 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) (200 mg, 0.63 mmol) using (Ph3P)2PdCl2 (68 mg) (Aldrich) and CuI (32 mg) (Aldrich) as catalyst in DMF (4 mL) and Et3N (4 mL) as solvent at 80° C. for 15 h, yielding rac-(Z)-1,3-dihydro-4-[3-hydroxy-3-(3-hydroxyphenyl)-1-propynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 82 mg, 31%).
