Abstract

A találmány tárgya eljárás N-(3,3-dimetilbutil)-a-L-aszpartil-L-fenil-alanin-metilészter tisztítására. A találmány értelmében úgy járnak el,hogy szennyezésként legalább aszpartil-L-fenilalanin-metilésztert kétfázisból álló oldószereleggyel érintkeztetnek, amelynél az egyik fázislegalább egy, vízzel homogén módon nem elegyedő szerves oldószerttartalmaz és a másik fázis víz, és így az N-(3,3-dimetilbutil)-a-L-aszpartil-L-fenilalanin-metilésztert a szerves fázisban elkülönítik.
