Fremgangsmåde til racematspaltning af tramadol

Separating the racemate of tramadol (I) comprises converting a tramadol salt into the base, separating the (-) enantiomer by precipitation with L-(+)-tartaric acid and isolating the (+)-tramadol enantiomer from the mother liquor from tartaric acid precipitation by releasing the base and subsequently...

Zusammenfassung:Separating the racemate of tramadol (I) comprises converting a tramadol salt into the base, separating the (-) enantiomer by precipitation with L-(+)-tartaric acid and isolating the (+)-tramadol enantiomer from the mother liquor from tartaric acid precipitation by releasing the base and subsequently converting into a salt which is different form the tartrate. The separated isomer prepared by the process is claimed per se.
