| titleOfInvention | Purification of (s,s)-8-benzyl-2,8-diazabicyclo[4.3.o]nonane using l-(+) tartaric acid in alcohol/water solvent mixture |
| abstract | A process for purifying (S,S)-8-benzyl--2,8-diazabicyclo[4.3.0]nonane, (see above formula) comprising: reacting a mixture of (S,S)-8-benzyl-2,8-diazabicyclo--[4.3.0]nonane and (R,R)-8-benzyl-2,8-diazabicylo--[4.3.0]nonane with L-(+)-tartaric acid in an alcohol/water solvent mixture; and converting (S,S)-8-benzyl-2,8-diazabicyclo-[4.3.0]nonane L-(+)-tartrate formed in the reacting step into free (S,S)-8-benzyl-2,8-diazabicyclo[4.3.0]nonane by reacting the (S,S)-8-benzyl-2,8-diazabicyclo[4.3.0]nonane L-(+)-tartrate with a base. |
