Abstract

"MéTODO PARA PREPARAçãO DO CITALOPRAM". A presente invenção refere-se a um método para a preparação de citalopram ou qualquer um de seus enântiomeros e sais em adição com ácido do mesmo, compreendendo a reação de um composto da fórmula (II), com um dieno tendo fórmula (III), onde X é O, S, SO~ 2~, -N=N-, -CO-O-, -O-CO-, ou com um dieno tendo fórmula (IV) onde R é alquila ou arila ou arilalquila opcionalmente substituída. A invenção também refere-se a intermediários usados em um processo novo para preparação de citalopram, bem como citalopram preparado de acordo com o novo processo."METHOD FOR THE PREPARATION OF CITALOPRAM". The present invention relates to a method for the preparation of citalopram or any of its enantiomers and salts in addition with acid thereof, comprising the reaction of a compound of formula (II), with a diene having formula (III), where X is O, S, SO ~ 2 ~, -N = N-, -CO-O-, -O-CO-, or with a diene having formula (IV) where R is alkyl or aryl or optionally substituted arylalkyl. The invention also relates to intermediates used in a new process for preparing citalopram, as well as citalopram prepared according to the new process.
