Lesdits composés se présentent sous la forme de (R)-énantiomères, (S)-énantiomères ou racémates sous forme d'une base libre ou de sels pharmaceutiquement tolérables de ceux-ci. L'invention concerne un procédé de leur préparation, des compositions pharmaceutiques contenant ces composés thérapeutiquement actifs et l'utilisation de ces composés actifs en thérapie.
