Combine 3-(2,2,3,3-tetrafluoropropoxy)tosylate (5.72 g, 17.2 mmol), 3-hydroxybenzaldehyde (2.44 g, 20.0 mmol), dimethylformamide (36 ml) and powdered potassium carbonate (3.03 g) and heat at 110° C. for 10 h. Cool to 20° C. Pass through a bed of aluminium-oxide-90 (57.2 g, 70–230 mesh, grade II–III, Brockmann: Merck # 1.01097) and elute with toluene (120 ml). Wash the eluted organic phase with 1N HCl (36 ml) and then water. Evaporate the organic layer under reduced pressure to give the title compound.
