[Synthesis and antidepressive activity study of aryl and heteroaryl carboxamides of benzylpiperazine]. / Synthèse et étude de l'activité antidépressive d'aryl et hétéroaryl carboxamides de la benzylpipérazine.

The synthesis of 44 original amide derivatives of benzylpiperazine and some analogues of befuraline and piberaline is reported. All compounds have been tested as antidepressive agents. According to the tests, amides 1, 24 and mainly 31 (dihydrobefuraline) seem to provide elevated antidepressive activity.
