Abstract:1-(2,3-Dichlorophenyl)piperazine hydrochloride is an important pharmaceutical intermediate. The starting material diethanolamine was halogenated to give β,β'-dihalogenated diethyiammonium hydrochloride,and then reacted with 2,3-dichloroaniline in aqueous solution without any catalyst to afford the target compound 1-(2,3-dichlorophenyl) piperazine hydrochloride. The product was characterized by 1H NMR and IR spectroscopy which was consistent with the proposed structures. |
Key words:1-(2,3-dichlorophenyl)piperazine hydrochloride;cyclo-condensation;diethanolamine |
