Abstract

"PROCESSO PARA PURIFICAR 4-AMINO-PIPERIDINAS 2,2,6,6-TETRASUBSTITUìDAS". A invenção está relacionada a um processo para purificar 4-amino-piperidinas 2,2,6,6-tetrasubstituídas produzidas das correspondentes piperidin-4-onas, e subsequente destilação. De acordo com a invenção, a 4-amino-piperidina 2,2,6,6-tetrasubstituída destilada é reagida com hidrogênio na presença de um catalisador hidratante ou deshidratante e a 4-amino piperidina é então separada da mistura de reação.
