Zusammenfassung:Disclosed herein is a novel recovery and recycling process of racemic 4-(4- dimethylamino)-1-(4'-fluorophenyl)-1-(hydroxybutyl)-3-(hydroxymethyl)- benzonitrile (hereinafter referred as cyanodiol). The racemic cyanodiol is an intermediate useful for preparation of Citalopram, Escitalopram or pharmaceutically acceptable salts thereof. L'invention concerne un nouveau procédé de récupération et de recyclage de 4- (4-diméthylamino)-1-(4 '-fluorophényl)-1-(hydroxybutyl)-3-(hydroxyméthyl)-benzonitrile racémique (ci-après appelé cyanodiol). Le cyanodiol racémique est un intermédiaire utile pour la préparation de Citalopram, d'Escitalopram ou de sels pharmaceutiquement acceptables de ceux-ci.
