Procedure

To a round-bottom flask equipped with a stirbar is added phenol 2G (R=4-Methyl-3-pentenyl) (5 g), tosylate 1H (R=n-pentyl) (5.95 g), cesium carbonate (7.45 g), and anhydrous dimethylforrnamide (50 mL). The reaction mixture is stirred overnight. It is then poured into 50 mL dilute HCl, and extracted with 1:1 hexanes:ethyl acetate. The combined organic layers are washed with brine and dried over potassium carbonate, and the solution is concentrated in vacuo. Filtration through silica gel using 10% ethyl acetate in hexanes gives the pure product.
