  • Manufacturing process for memantine
    Patent number: 9452971
    Abstract: A method for manufacturing 3,5-dimethyl-1-adamantanamine of the present invention comprises: (i) a step of reacting 3,5-dimethyl-1-adamantanol with an acid and nitrile in an organic solvent to obtain a reaction solution; (ii) a step of adding water to the reaction solution obtained in step (i) to obtain 1-amido-3,5-dimethyladamantane; and (iii) a step of hydrolyzing 1-amido-3,5-dimethyladamantane obtained in step (ii) in the presence of an alcohol-containing solvent and an inorganic base.
