METHOD FOR PURIFYING COMPOUNDS COMPRISING AMINO GROUPS

摘要

Method for purifying compounds (I) containing amino groups from a polar phase A, where (I) is converted by reaction with an aldehyde or ketone (II) into the corresponding imine (III) which is insoluble or sparingly soluble in the polar phase A, and then the imine (III) is converted to a nonpolar phase B and separated off from phase A, and then the compound containing amino groups is recovered from the imine (III).
