Versuchsvorschrift

In a manner analogous to that described in example 24 a), the alkylation of the 5-hydroxy-pyridine-2-carboxylic acid methyl ester with potassium carbonate and trifluoro-methanesulphonic acid 2,2,3,3,3-pentafluoropropyl ester yielded the 5-(2,2,3,3,3-pentafluoro-propoxy)-pyridine-2-carboxylic acid methyl ester as a light yellow oil. MS (ISP): m/z=285 [M]+.
