Abstract

The present invention relates to a process for separating an enantiomer mixture of (R)- and (S)-3-amino-1-butanol optionally protected on the oxygen atom, and to a process for preparing essentially enantiomerically pure (R)-3-amino-1-butanol which optionally bears a protecting group on the oxygen atom.
