Reaction Steps
Using Method D above, 3-hydroxy-3-(2-thiophenyl)-1-propyne (102 mg, 0.74 mmol) (prepared by the addition of ethynylmagnesium chloride (Aldrich) to 2-thiophenecarboxaldehyde (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 (126 mg, 0.39 mmol) (Starting Material 1) using (Ph3P)2PdCl2 (35 mg) (Aldrich) and CuI (17 mg) (Aldrich) as catalyst in DMF (3 mL) and Et3N (3 mL) as solvent at 70° C. for 18 h, yielding rac-(Z)-1,3-dihydro-4-[3-hydroxy-3-(2-thiophenyl)-1-propynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one. (Yield 105 mg, 71%).
