Procedure
To 900 ml of toulene were added 300 mmol of the obtained 5-hydroxy-1,3-adamantanedicarboxylic acid, 900 mmol of n-butanol and 30 mmol of sulfuric acid, and the resultant mixture was stirred under reflux of toluene for 5 hours. The reaction mixture was concentrated and subjected to column chromatogrpahy on a silica gel to give di-n-butyl 5-hydroxy-1,3-adamantanedicarboxylate in yield of 85.5% at a conversion rate from 5-hydroxy-1,3-adamantanedicarboxylic acid of 95%.
