Process for the preparation of (3-fluoropyridin-2-yloxy)phenoxypropionic acids

(3-Fluoropyridin-2-yloxy)phenoxypropionic acids of formula I STR1 wherein X is hydrogen, fluoro, chloro, bromo or trifluoromethyl and Y is hydrogen, sodium or potassium, are prepared by reacting a compound of formula II STR2 wherein X and Y are as defined for formula I, in an anhydrous mixture of hydrogen fluoride, dimethylsulfoxide and a diazotising agent under normal pressure, and converting the diazonium fluoride so produced by thermal decomposition into the (3-fluoropyridin-2-yloxy)phenoxypropionic acid of formula I.
