摘要:
The present invention relates to a process for preparing halogenated pyridine derivatives of the formula (II) proceeding from compounds of the formula (I) via intermediates of the formula (IIIa) or (IIIb) where the radicals Q and W are each independently halogen, R2 is halogen or —O-pivaloyl, and Y is halogen, CO2R1 or NO2, where R1 is (C1-C6)-alkyl or (C1-C6)-haloalkyl.
