Summary:A novel process for racemization of (R)-3-cyano-5 -methyl hexanoic acid ethyl ester directly to (RS)-3-cyano-5 -methyl hexanoic acid has been developed through a base catalyzed mechanism in a specific solvent system. L'invention concerne un nouveau procédé de racémisation d'ester éthylique d'acide (R)-3-cyano-5-méthylhexanoïque directement en acide (RS)-3-cyano-5-méthylhexanoïque qui a été développé par un mécanisme catalysé par une base dans un système de solvant spécifique.
