Reaction Steps

A suspension 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), K2CO3 (25 mg, 0.180 mmol), (Ph3P)4Pd (5 mg, 0.004 mmol) (Aldrich), and 3-(trifluoromethyl)phenylboronic acid (20 mg, 0.110 mmol) (Aldrich) in 2.5 mL of a 1.5:1 mixture of 1,2-dimethoxyethane:distilled water was heated at reflux under a nitrogen atmosphere for 14 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 then 40% ethyl acetate-hexanes elution) to yield pure (Z)-1,3-dihydro-3-[(1H-pyrrol-2-yl)methylene]-4-(3-trifluoromethylphenyl)-2H-indol-2-one (yield 18 mg, 56%) as a yellow solid (mp 197-198° C.).
