    • The invention encompasses processes for obtaining pure armodafinil substantially free of disulfide impurities that is suitable for use on an industrial scale. In particular, a processes for purifying armodafinil from bis(diphenylmethyl)disulfide comprising: dissolving crude armodafinil in ethanol to form a solution; adding a solvent selected from the group consisting of linear or branched C5-C8 alkyl, linear or branched C5-C8 ether, and mixtures thereof to the solution to form a reaction mixture; cooling the reaction mixture; and isolating pure armodafinil from the reaction mixture.
    • 本发明包括用于获得基本上不含适于在工业规模上使用的二硫化物杂质的纯的甲状腺素的方法。 特别是从二(二苯基甲基)二硫化物中净化犰狳的方法,其特征在于:将粗制的甲状腺素溶于乙醇中形成溶液; 向溶液中加入选自直链或支链C5-C8烷基,直链或支链C5-C8醚及其混合物的溶剂,形成反应混合物; 冷却反应混合物; 并从反应混合物中分离纯的armodafinil。
