Vorschrift

{4-Hydroxy-3-[4-nitro-2-(2,2,2-trifluoro-ethylsulfanylmethyl)-phenoxy]-phenyl}-acetic acid (3.6 mmol) and hydrogen chloride (4N in 1,4-dioxane) were combined in EtOH and stirred at 80° C. for 3 hours. After concentrating to dryness, the residue was purified by silica gel chromatography to give {4-hydroxy-3-[4-nitro-2-(2,2,2-trifluoro-ethylsulfanylmethyl)-phenoxy]-phenyl}-acetic acid methyl ester.
