The present invention relates to a process for preparing fluoromethyl-substituted heterocyclic compounds of the general formula (I) n n n n n n n n n n in which R 1 is H or F; R 2 is an -[A-O] m —R 3 group in which A is C 2 -C 4 -alkanediyl, R 3 is C 1 -C 4 -alkyl and m is 1 or 2;n nby converting the corresponding chloromethyl-substituted compounds (II) in the presence of fluorinating agents,n nto processes for preparing the chloromethyl-substituted compounds (II),n nto processes for preparing amides of the general formula (IV)n n n n n n n n n n n and to compounds of the general formulae (I) and (II). |
