Procedure

Dess-Martin periodinane (1.30 g) is added to a solution of 2-benzyl-2-aza-bicyclo[3.3.1]nonan-6-ol (0.60 g) in dichloromethane (15 mL) chilled in an ice bath. The cooling bath is removed and the solution is stirred at ambient temperature for 1 h. Then, the solution is diluted with dichloromethane and washed with a mixture of aqueous Na2S2O3 solution and aqueous NaHCO3 solution. The solution is dried (Na2SO4) and the solvent is removed. The residue is purified by chromatography on silica gel (dichloromethane/methanol 1:0->2:1).
