As intermediates for the preparation of aminoalkylbenzene derivatives, compounds of the general formula II <IMAGE> in which the substituents attached to the benzene ring are in the ortho, para or meta position with respect to one another, and in which R1 and R2, which may be identical or different, represent hydrogen or lower alkyl, cycloalkyl, aralkyl or lower alkenyl groups, or lower alkyl groups which are interrupted by an oxygen atom or a group <IMAGE> in which R4 has the meaning hydrogen or lower alkyl, or R1 and R2 form, together with the nitrogen atom to which they are attached, a heterocyclic ring which may contain the hetero functions -O- and <IMAGE>, represents -O-, -S-, -CH2- or <IMAGE>, in which R5 has the meaning hydrogen or lower alkyl, m is an integer from 2 to 4, n has the value 0, 1 or 2 and Alk represents a straight-chain or branched alkylene chain having from 1 to 6 carbon atoms, and their acid addition salts with inorganic and organic acids.
