Reaction Steps

A solution of (Z)-1,3-dihydro-4-iodo-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (100 mg, 0.298 mmol) (Starting Material 1), 2M aqueous Na2CO3 solution (342 μL, 0.684 mmol), (Ph3P)4Pd (17 mg, 0.015 mmol) (Aldrich), and 4-methoxyphenylboronic acid (52 mg, 0.342 mmol) (Aldrich) in 3 mL of a 2:1 mixture of 1,2-dimethoxyethane:distilled water was heated at 100° C. under a nitrogen atmosphere for 20 h. The reaction mixture was diluted with ethyl acetate, and the organic layer was washed with distilled water. The organic layer was concentrated in vacuo to provide a crude yellow-brown solid. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 25% ethyl acetate-hexanes elution) yielded pure (Z)-1,3-dihydro-4-(4-methoxyphenyl)-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (89.3 mg, 82%) as a yellow solid (mp 222-223° C.).
