VERFAHREN ZUR HERSTELLUNG VON BASISCHEN OXIMAETHERN

An improved process for the preparation of basic oxime ethers of the general Formula I /wherein R is a phenyl group optionally substituted by one to three halogen atom/s/ and/or lower alkoxy group/s/; R and R each are hydrogen or together from a valence bond; A is lower alkylene; R and R each stand for hydrogen or lower alkyl or together with the adjacent nitrogen atom they are attached to form a 5-8 membered heterocyclic ring which may optionally contain a further oxygen or nitrogen atom and/or may be optionally substituted by lower alkyl, phenyl or phenyl-lower alkyl, and n is 3, 4, 5, 6 or 7/ and acid addition salts thereof comprises reacting an oxime of the general Formula II with a compound of the general Formula III (where Hal is a halogen atom) or an acid addition salt thereof in the presence of an alkali metal lower alkoxide and an aromatic organic hydrocarbon solvent.
