6-Oxo-2-piperidinecarboxylic acid has been resolved via direct crystallization of pure S-6-oxo-2-piperidinecarboxylic acid dehydroabietylammonium salt from a solvent system consisting of dimethylformamide, cyclohexane and acetone. The S-enantiomer is a required component for making certain tripeptides related to thyrotropin releasing hormone (TRH) which are central nervous system stimulants.
