Procedure

A solution of 5-hydroxy-2-adamantanone (2.6 g, 15.66 mmoles) in dichloromethane (DCM) (50 mL) was treated with dimethylaminopyridine (DMAP) (2.1 g, 17 mmoles) and acetic anhydride (2.3 mL, 23 mmoles) and stirred overnight at 50° C. The solvent was removed under reduced pressure and the residue was partitioned between water and ethyl acetate. The aqueous layer was extracted twice with ethyl acetate. Combined organic extracts were washed with water, dried (MgSO4) and filtered. The filtrate was concentrated under reduced pressure to provide the title compound as an off-white solid.
