15 mmol of aluminiumlitium hydroxide was suspended in 15 ml of tetrahydrofuran (THF) in a nitrogen atmosphere. To the solution was slowly added 10 mmol of the 1-carboxy-3-adamantanol obtained in Preparation Example 5 while the temperature of the solution was maintained at less than 10° C. or below by ice water bath. After the temperature of the mixture was raised to room temperatures, the mixture was refluxed for 16 hours. And, as the result, the 1-carboxy-3-adamantanol was converted into a 1-hydroxymethyl-3-adamantanol (yield: 95%) with a conversion of 99%.
