Abstract
(EN)
This invention broadly relates to a method for synthesizing ll-(4-[2-(2- hydroxyethoxy)ethyl]-piperazinyl)-dibenzo[b,f][l,4]thiazepine hemifumarate salt (Quetiapine hemifumarate) and the intermediate 11- piperazinyldibenzo[b,f][l,4]thiazepine dihydrochloride using phosphorous oxychloride in presence of non-aromatic solvent and condensing with piperazine.
(FR)
La présente invention concerne, d'une manière générale, un procédé de synthèse du sel d'hémifumarate de ll-(4-[2-(2- hydroxyéthoxy)éthyl]-pipérazinyl)-dibenzo[b,f][l,4]thiazépine (hémifumarate de Quetiapine) et de l'intermédiaire dichlorhydrate de 11-pipérazinyldibenzo[b,f][l,4]thiazépine en utilisant de l'oxychlorure de phosphore en présence d'un solvant non aromatique et en condensant avec de la pipérazine.
