Process for the preparation of 5-chloro-1-(4-fluorophenyl)-3-(1,2,3,6-tetrahydropyridin-4-yl)indole and method of manufacturing sertindole

摘要

A process of manufacturing sertindole comprising reacting 5-chloro-1-(4-fluorophenyl)indole with 4-piperidone in a mixture of an acetic acid and concentrated HCl; reduction of the resulting 5-chloro-1-(4-fluorophenyl)-3-(1,2,3,6-tetrahydropyridin-4-yl)indole and reaction of this compound with 1-(2-chloroethyl)-2-imidazolidinon in order to obtain sertindole.
