Procedure

Tetrakis(acetonitrile)copper(I) hexafluorophosphate (4.62 g, 12.4 mmol), cesium carbonate (32 g, 98 mmol), 2-bromobenzoic acid (10g, 49. 7 mmol) and 2-methoxyphenol (6.17 g, 49.7 mmol) were combined in toluene (100 mL), and the mixture was heated to reflux for 15 hr. Ethyl acetate (200 mL) and 1N HCl (200 mL) were added, and the organic layer was separated. The organic layer was dried over MgSO4, filtered, and evaporated to yield 16.8 g of Compound 1a. The residue was used without further purification. MS m/z (M-H)− 243.1.
