요약서:
(EN) A method for the preparation of pioglitazone O,O'-dibenzoyl-L-tartrate wherein the content by weight of pioglitazone consists of at least 95 % by weight of the 5R enantiomer and less than 5 % of the 5S enantiomer, which method comprises: (1a) adding seed crystals of 5R- pioglitazone O,O'-dibenzoyl-l-tartrate to a rnethanol-water solution of racemic pioglitazone hydrochloride and O,O'-dibenzoyI-L-tartaric acid, thereby precipitating pioglitazone O,O'- dibenzoyl-L-tartrate;(1b) recovering said precipitate from step (1a); (1c) forming a solution of the precipitate from step (1b) in a solvent mixture of methanol, acid and water and mixing into to the resultant solution seed crystals of 5R-pioglitazone O,O'-dibenzoyl-L-tartrate, thereby precipitating pioglitazone O,O'-dibenzoyl-L-tartrate; (1d) recovering said precipitate from step (1c); (1e) repeating steps (1c) and (1d), the recovered product being the desired pioglitazone O,O'-dibenzoy! tartrate wherein the content by weight of pioglitazone consists of at least 95 % by weight of the 5R enantiomer and less than 5 % of the 5S enantiomer. Also disclosed is a modification of the method in which step 1(e) is omitted.
(FR) La présente invention concerne un procédé de préparation de O,O'-dibenzoyl-L-tartrate de pioglitazone dans lequel le contenu en poids de pioglitazone est constitué d'au moins 95 % en poids de l'énantiomère 5R et moins de 5 % de l'énantiomère 5S, ledit procédé comprenant : (1a) l'ajout de cristaux d'amorce de O,O'-dibenzoyl-l-tartrate de 5R-pioglitazone à une solution de méthanol-eau de chlorhydrate de pioglitazone racémique et d'acide O,O'-dibenzoyl-L-tartrique, de manière à précipiter le O,O'-dibenzoyl-L-tartrate de pioglitazone; (1b) récupérer ledit précipité de l'étape (1a); (1c) former une solution du précipité de l'étape (1b) dans un mélange de solvant de méthanol, d'acide et d'eau et en mélangeant dans la solution résultante les cristaux d'amorce de O,O'-dibenzoyl-L-tartrate de 5R-pioglitazone, de manière à précipiter le O,O'-dibenzoyl-L-tartrate de pioglitazone; (1d) récupérer ledit précipité de l'étape (1c); (1e) répéter les étapes (1c) et (1d), le produit récupéré étant le O,O'-dibenzoyltartrate de pioglitazone souhaité où le contenu en poids de pioglitazone est constitué d'au moins 95 % en poids de l'énantiomère 5R et moins de 5 % de l'énantiomère 5S. La présente invention concerne en outre une modification du procédé dans lequel l'étape 1(e) est omise.
