2-(4-Hydroxy-3-methoxyphenyl)acetonitrile (0.54 g, 3.31 mmol) in THF (10 mL) was treated with 3-cyclopentylpropan-1-ol (0.424 g, 3.31 mmol), triphenylphosphine (1.128 g, 4.3 mmol) and cooled in an ice bath to 0° C. DIAD (0.785 ml, 4 mmol) was added to the reaction mixture dropwise over the period of 5 min, and the reaction was left stirring slowly warming to room temperature over 18 hours. The reaction mixture was concentrated. Purification by flash chromatography (silica gel, 0-40% EtOAc/hexanes) afforded 0.871 g (96%) of 2-(4-(3-cyclopentylpropoxy)-3-methoxyphenyl)acetonitrile.
