Reaction Steps
A solution of (Z)-1,3-dihydro-4-iodo-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (30 mg, 0.089 mmol) (Starting Material 1), 2M aqueous Na2CO3 solution (89 μL , 0.178 mmol), (Ph3P)4Pd (5 mg, 0.004 mmol) (Aldrich), and 3-chlorophenylboronic acid (16 mg, 0.102 mmol) (Aldrich) in 3 mL of a 2:1 mixture of 1,2-dimethoxyethane:distilled water was heated at reflux under a nitrogen atmosphere for 16 h. The reaction mixture was allowed to cool to room temperature and then directly purified by flash chromatography (Merck Silica gel 60, 230-400 mesh, 25% ethyl acetate-hexanes elution) to provide pure (Z)-4-(3-chlorophenyl)-1,3-dihydro-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (26 mg, 90%) as a yellow solid (mp 165-167° C.).
