Aromatic derivatives comprising an aminoalkoxy chain, the salts thereof, the process for preparing these derivatives and salts and the application thereof in therapeutics

An aminoalkoxy aromatic derivative, corresponding to the general formula:

• ##STR437## in which:
• R represents a hydrogen or halogen atom, a methyl or alkoxy group in which the alkyl residue contains 1 to 4 carbon atoms, or a benzyloxy group;
• n takes the value 1 when R is H and 1 or 2 when R is different from H;
• m takes the value 2 or 3;
• A represents a chain having any one of the following structures:
• ##STR438## the aromatic group Ar being linked to position 1 of this chain;
• R.sub.1 and R.sub.2 form, in conjunction with the nitrogen atom to which they are linked, a radical chosen from the following;
• pyrrolidino, piperidino, hexamethyleneimino, and morpholino;
• and
• Ar represents:
• either a benzene group of structure:
• ##STR439## in which R.sub.3 represents a halogen atom or a nitro or methyl group, R.sub.4 =alkoxy with 1 to 4 carbon atoms, p=0, 1 or 2;
• q=1, 2, 3, 4;
• p+q.ltoreq.4;
• or a naphthalene or benzodioxannic group respectively of structure;
• ##STR440## where R.sub.4 has the same meanings as previously defined;
• as well as its mineral or organic acid addition salts.
