Toluene → HCID 69420577, compound

Participants

Reaction Steps

A 2-necked flask was equipped with a reflux condenser and charged with 117c (1.14 g, 2.78 mmol) and tetrakis(triphenylphosphine)palladium (308 mg, 0.28 mmol). Anhydrous toluene (15 mL) and tributylvinyltin (0.85 mL, 2.91 mmol) were added, and the reaction was heated to reflux under nitrogen for 16 h. The solution was cooled to RT and EtOAc (50 mL) was added. The mixture was washed with H2O (25 mL) and brine (25 mL), and dried over anhydrous MgSO4. The solvents were evaporated, and the resulting oil purified by flash chromatography over silica gel(0% to 25% EtOAc/hexanes) to provide 770 mg (78%) of [4-chloro-3-(3-cyano-5-vinyl-phenoxy)-2-fluoro-phenyl]-acetic acid ethyl ester (118).
