The present invention relates to a process for preparing fluoromethyl-substituted heterocyclic compounds of the general formula (I)
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;
by converting the corresponding chloromethyl-substituted compounds (II) in the presence of fluorinating agents,
to processes for preparing the chloromethyl-substituted compounds (II),
to processes for preparing amides of the general formula (IV)
and to compounds of the general formulae (I) and (II).
