Abstract
By means of a new process for the resolution of racemic 3-aminopentanenitrile, enantiomerically enriched 3-aminopentanenitrile or its salts can be obtained. For this, racemic 3-aminopentanenitrile is reacted with an enantiomerically enriched organic acid and one of the two diastereomeric salts formed is separated off and then converted into the enantiomerically enriched 3-aminopentanenitrile or its salts.
