The present invention relates to processes comprising a combined racemization and stereoselective reductive amination step in which an aldehyde compound of formula (I) is contacted with an (R)-selective ω-transaminase or an (S)-selective ω-transaminase to racemize the compound of formula (I) and obtain an amine compound of formula (II). These processes are useful for the preparation of precursors of pharmaceutically active agents such as brivaracetam and pregabalin.
