2-Iodo-terephthalic acid dimethyl ester (10 g, 31 mmol), phenol (3.23 g, 34 mmol), tetrakis-acetonitrilecopper hexafluorophosphate (2.9 g, 7.8 mmol), and cesium carbonate (10.2 g, 31 mmol) were added to a 1 L 3-neck round bottom flask equipped with a mechanical stirrer, a reflux condenser and containing toluene (350 mL). The reaction was refluxed 5 h under nitrogen with stirring. After cooling, EtOAc (200 mL) was added and the mixture was filtered. The filtrate was concentrated to afford the crude title compound (9.2 g) that was used without purification.
