such as PK11195 and Ro 5-4864 were found more than twenty years ago in the course of research on neurobiology. These ligands were instrumental in pointing out an involvement of the peripheral-type benzodiazepine receptor (PBR) in apoptosis processes. With in mind an improvement of the solubility of PK11195 in biological media, we report here improved reaction conditions for the palladium-based arylation

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.
