Methods for the racemization of an enantiomer of a 2,3-benzodiazepine molecule into the corresponding racemic mixture under either basic or acidic conditions are described. Furthermore, the invention relates to the conversion of an enantiomer of tofisopam or its metabolites to the corresponding opposite enantiomer.
