| description | The present invention discloses a method for resolving cyclohexylphenyl glycolic acid and the preparation of optically active phenylcyclohexyl glycolate esters. More particularly, the invention provides a process for preparation of optically active R-oxybutynin hydrochloride with high enantiomeric purity of greater than 99%.
La présente invention concerne un procédé de résolution d'acide cyclohexylphénylglycolique et la préparation d'esters de phénylcyclohexylglycolate optiquement actifs. Plus particulièrement, l'invention concerne un procédé de préparation de chlorhydrate de R-oxybutynine optiquement actif ayant une pureté énantiomérique élevée supérieure à 99 %. |
