| titleOfInvention |
Process for the preparation of d-threo-(r,r)-methyl phenidate and recycling of undesired enantiomers by epimerisation |
| abstract |
The present invention pertains to a process for obtaining a single enantiomer, d or l, of threo-methylphenidate, comprising resolution of a mixture of the enantiomers; racemisation of the unwanted enantiomer, to give a mixture of all four stereoisomers; and separation of the erythro stereoisomers, to leave the same mixture of enantiomers for resolution. |
