Abstract
Compounds with the formula: ##STR1## in which R.sub.1 and R.sub.2 represent independently, a linear or branched alkyl, cycloalkyl, phenylalkyl or cycloalkylalkyl group. R.sub.1 and R.sub.2 may also represent an alkenyl or alkynyl group. R.sub.1 and R.sub.2 may also represent a group of the formula --R.sub.3 --Z--R.sub.4 in which R.sub.3 represents an alkylene group, on condition that at least 2 carbon atoms separate the nitrogen atom from the group Z; R.sub.4 represents an alkyl group, and Z an atom of oxygen, sulphur or the group >N--R.sub.5, R.sub.5 representing a hydrogen atom or an alkyl group. R.sub.1 and R.sub.2 may form, with the nitrogen atom to which they are attached, a heterocyclic ring. Ar represents a phenyl, pyridyl or thienyl group, or a substituted phenyl group, A and B representing independently, N or CH--, the group C representing the residue of a benzene or thiophene ring. These compounds can be used as medicaments, in particular, for the various applications of benzodiazepines.
