Zusammenfassung:Provided here are methods of manufacture of viloxazine and its various salts, as well as viloxazine-related compounds, such as novel intermediate reaction products and polymorphs thereof. In particular, the methods provide a substantially pure API of viloxazine HC1 while avoiding undesirable impurities. The methods further provide for separating, identifying, and characterizing novel polymorphs of viloxazine. Further provided are methods for synthesis and identification and characterization of novel intermediates of viloxazine, as well as for some important metabolites and precursors of metabolites of viloxazine. L'invention concerne des procédés de fabrication de viloxazine et de ses divers sels, ainsi que des composés apparentés à la viloxazine, tels que de nouveaux produits réactionnels intermédiaires et des polymorphes de celle-ci. En particulier, les procédés fournissent un Ingrédient Pharmaceutique Actif (API) sensiblement pur de viloxazine HCl tout en évitant des impuretés non désirables. Les procédés concernent en outre la séparation, l'identification et la caractérisation de nouveaux polymorphes de viloxazine. L'invention concerne en outre des procédés de synthèse et d'identification et de caractérisation de nouveaux intermédiaires de viloxazine, ainsi que certains métabolites et précurseurs de métabolites importants de viloxazine.
