| description | A process for resolving racemic (±)-10,l l-dihydro-10-hydroxy-5H-dibenz[b,f]azepine-5- carboxamide comprising reacting (±)-10,l l-dihydro-10-hydroxy-5H-dibenz[b,f]azepine-5- carboxamide with S-ibuprofen or a pharmaceutically acceptable salt thereof to form a mixture of the SS and SR diastereomer esters of 10,l l-dihydro-10-hydroxy-5H-dibenz[b,f]azepine-5- carboxamide, followed by separating the SS-ibuprofen ester from the SR ibuprofen ester, and removal of the S-ibuprofen moiety to form S-(+)-10,l l-dihydro-10-hydroxy-5H- dibenz[b,f]azepine-5-carboxamide with a chiral purity greater than 90%.
L'invention concerne un procédé permettant de résoudre racémique (±)-10,11-dihydro -10-hydroxy -5 h-dibenz / b, f / azépine -5-carboxamide consistant notamment à faire réagir (±)-10,11-dihydro -10-hydroxy -5 h-dibenz / b, f / azépine -5-carboxamide avec S-ibuprofène ou un sel pharmaceutiquement acceptable de celui-ci pour former un mélange SS et SR diastéréomère esters de 10,l l-dihydro-10-hydroxy-5H-dibenz[b,f]azépine-5- carboxamide, puis à séparer le SS-ibuprofène ester du SR ibuprofène ester, et à évacuer la fraction du S-ibuprofène pour former S-(+)-10,l l-dihydro-10-hydroxy-5h- dibenz[b,f]azépine-5-carboxamide d'une pureté chirale dépassant 90%. |
