More detailed explanations on Reaction Formula 1 are as follows: 4-oxoadamantane-1-carboxylic acid (1) is treated with oxalic chloride and ammonia water to prepare 4-oxoadamantane-1-carboxylic acid amide (2), and the resulting compound is treated with ammonia and subjected to a reduction reaction by using hydrogen to produce 4-aminoadamantane-1-carboxylic acid amide (3). 4-aminoadamantane-1-carboxylic acid amide thus prepared is a mixture of (E) and (Z) types, which is made into a salt form by using hydrochloric acid and then subjected to recrystallization by using acetonitrile and water to yield a pure (E) type of 4-aminoadamantane-1-carboxylic acid amide (4).
