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 HCl 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.
这里提供的是维洛沙嗪及其各种盐类以及维洛沙嗪相关化合物(如新型中间反应产物及其多晶型)的制造方法。特别是,这些方法提供了基本纯净的盐酸维洛沙嗪原料药,同时避免了不需要的杂质。这些方法还提供了分离、鉴定和表征新型多晶型维洛沙嗪的方法。此外,还提供了合成、鉴定和表征维洛沙嗪新型中间体以及维洛沙嗪的一些重要代谢物和代谢物前体的方法。
