Abstract

Det er her tilveiebrakt nye fremgangsmåter for fremstilling av mellomprodukter som kan være nyttige ved fremstilling av 5-Ht1b reseptorantagonister som er nyttige ved behandling av depresjon, angst og andre beslektede sykdommer. De foreliggende fremgangsmåtene kan gi forbedrete utbytter, renhet, forenklet fremstilling og isolering av mellomprodukter og sluttprodukt og industrielt mer nyttige reaksjonsbetingelser og bearbeidbarhet.New methods are provided here for the preparation of intermediates which may be useful in the preparation of 5-Ht1b receptor antagonists useful in the treatment of depression, anxiety and other related diseases. The present methods can provide improved yields, purity, simplified preparation and isolation of intermediates and end products, and industrially more useful reaction conditions and processability.
