    Abstract: The present invention relates to a process for preparing compounds of the formula I,

    wherein
    R 1 and R 2
    are each independently from one another selected from hydrogen, fluorine, bromine, chlorine and trifluoromethyl,
    R 3
    is selected from fluorine chlorine and trifluoromethyl,
    R 4
    is selected from C 1 -C 4 -alkyl, and
    X
    is either -OR 5 or -NR 6 R 7 , wherein R 5 is selected from C 1 -C 4 -alkyl, and R 6 and
    R 7
    are each independently from one another selected from C 1 -C 4 -alkyl,

    which comprises the reaction of a compound of the formula II

    with a reagent of the formula III,

    wherein the variables R 1 , R 2 , R 3 , R 4 , R 5 and X given in formulae II and III have the above defined meanings,
    in the presence of a catalyst selected from Brønsted acids, ammonium salts of Brønsted acids and Lewis acids;
    wherein the reaction is performed essentially in the absence of a carboxylic acid anhydride.
