Vorschrift

9.5 g (43.0 mmol) of methyl 2,4-dichloro-3-hydroxybenzoate in 240 ml of acetonitrile were admixed with 8.6 g (62.2 mmol) of potassium carbonate and then with 9.5 ml (52.8 mmol) of nonafluoro-n-butanesulfonyl chloride. The reaction mixture was stirred at room temperature (RT) for 16 h. For workup, the contents were poured onto ice-water and the mixture was extracted with ethyl acetate. The organic phase was dried and the filtrate was freed of the solvent on a rotary evaporator. The residue was purified by chromatography, which gave 3.5 g of clean product.
