Aromatic amine compounds, Their method of preparation and pharmaceutical compositions in which they are present

A compound of the formula ##STR232## in which:

• G is hydrogen, a tetrahydropyranyl group or a methanesulfonyl group;
• R.degree..degree. is hydrogen, a methyl group or a group (CH.sub.2).sub.n --L.degree..degree., in which n is a number from 2 to 6 and L.degree..degree. is hydrogen or an amino group which is free or protected by an N-protecting group;
• or one of its salts,
• wherein
• m is 2 or 3;
• Ar' independently is a thienyl group;
• a phenyl group which is unsubstituted or mono- or disubstituted by a halogen atom, by a C.sub.1 -C.sub.3 alkyl, by a trifluromethyl, by an alkoxy in which the alkyl is C.sub.1 -C.sub.3, by a hydroxyl or by a methylenedioxy;
• or an imidazolyl group;
• it is also possible for Ar' to be a benzothienyl group which is unsubstituted or substituted by a halogen;
• a naphthyl group which is unsubstituted or substituted by a halogen;
• a biphenyl group;
• or an indolyl which is unsubstituted or substituted on the nitrogen by a benzyl group;
• Q is hydrogen, a C.sub.1 -C.sub.4 alkyl group or an aminoalkyl group of the formula --(CH.sub.2).sub.q --Am', in which q is 2 or 3 and Am' is a piperidino, 4-benzylpiperidino or dialkylamino group, it being possible for each alkyl to contain from 1 to 4 carbon atoms;
• T is a group selected from ##STR233## W being an oxygen or sulfur atom;
• and Z is either hydrogen, or M or OM when T is the group --C(.dbd.O)--, or M when T is the group --C(.dbd.W)--NH--, M being hydrogen;
• a linear or branched C.sub.1 -C.sub.6 alkyl;
• a phenyl or phenylalkyl in which the alkyl group contains from 1 to 3 carbon atoms and which is unsubstituted or mon- or poly-substituted on the aromatic ring by a halogen, a hydroxyl, an alkoxy having 1 to 4 carbon atoms or an alkyl having 1 to 4 carbon atoms;
• a pyridylalkyl in which the alkyl group contains from 1 to 3 carbon atoms;
• a naphthylalkyl in which the alkyl group contains from 1 to 3 carbon atoms;
• a pyridylthioalkyl in which the alkyl group contains from 1 to 3 carbon atoms;
• a styryl;
• a 1-methylimidazol-2-ylthioalkyl in which the alkyl group contains from 1 to 3 carbon atoms;
• a 1-oxophenyl-3-indan-2-yl;
• or an unsubstituted or mono- or poly-substituted aromatic or hetero-aromatic group;
• provided that when m=3, G is hydrogen, Ar' is an unsubstituted phenyl group, Q is an ethyl group, T is ##STR234## and Z is a methyl group, then R.degree..degree. is different from hydrogen.
