Procedure

The same operations as conducted in Example 1 were repeated, except that the reaction mixture temperature after dropwise addition of nitric acid was set to 80° C. In the first carboxylation reaction step, the conversion of 1-adamantanol was found to be 99.0% and 1-adamantane carboxylic acid was generated in a reaction yield of 97%. In the second oxidation reaction step, the conversion of 1-adamantane carboxylic acid was found to be 98.0% and white crystals of 3-hydroxy adamantane-1-carboxylic acid (9.8 g, yield: 25.2%) were obtained.
