Process for the preparation of ortho-substituted arylcarboximidoesters

摘要

The present invention describes a process for the preparation of compounds of the formula I ##STR1## in which R denotes fluorine, chlorine, bromine or (C.sub.1 -C.sub.4)alkyl,PPR.sup.1 denotes (C. sub.1 -C.sub.4)alkyl,PPR.sup.2 denotes H, methyl, methoxy, fluorine, chlorine, bromine or trifluoromethyl, and PPX denotes Cl or Br, by reaction of nitriles of the formula II ##STR2## with alcohols of the formula III and hydrogen chloride or bromide, which comprises carrying out the reaction under pressure at temperatures from - C. to +50 C., if appropriate in the presence of a diluent, ad subsequently converting the resulting hydrochloride or hydrobromide into the free base.
