Procedure
A 500 mL 2-neck flask equipped with thermometer and gas inlet charged with potassium carbonate (27.6 g), hydroxy benzaldehyde (13.4 g), and 3-(perfluorooctyl)propyl iodide (58.8 g) in DMF (200 mL) was heated to 65° C. (internal temperature). The mixture was stirred at 65° C. until the reaction was complete. The reaction mixture was cooled to room temperature. Water (300 mL) and ether (300 mL) were added and the mixture stirred vigorously for 5 min. The layers were separated and the organic layer retained. The aqueous layer was extracted with ether (3×200 mL). The combined organic layers were washed with water (2×100 mL), Na2S2O3 (1×100 mL), 2.5 N NaOH (3×100 mL), and aqueous NaCl (1×100 mL). The organic layer was dried over MgSO4, filtered and concentrated. The product was further dried under high vacuum for 5 h to give desired product (53 g, 91% yield). The structure of the product was characterized 1H NMR.
