Procedure

To a solution of 2-(3-hydroxyphenyl)propionitrile (0.118 g, 0.80 mmol), prepared as above described, in dry CH2Cl2 (6 mL were sequentially added, molecular sieves (4 Å), CuOAc (0.145 mg, 0.80 mmol) and pyridine (0.33 mL, 4.0 mmol). After stirring 20 min commercial 2-methoxyphenylboronic acid (0.243 g 1.60 mmol) was added. The reaction mixture was stirred overnight at room temperature. The reaction mixture was cooled to 0° C., 0.5N HCl added and the organic phase washed (3×10 mL) with 0.5N HCl. After drying over Na2SO4 and solvent evaporation under reduced pressure a residue was obtained that, after flash chromatography (eluent mixture n-hexane/EtOAc 9:1), afforded 2-{3-[(2-methoxy)phenoxy)phenyl]propionitrile as pale yellow oil (0.172 g, 0.68 mmol). Yield 85%.
