To a solution of tert-butyl [3-(hydroxymethyl)cyclohexyl]carbamate (0.51 g, 2.2 mmol) in methylene chloride (10 mL) at 0° C. was added Dess-Martin periodinane (1.1 g, 2.7 mmol). The mixture was stirred at room temperature for 2 h. The reaction was quenched with aq. 1N NaOH solution and extracted with methylene chloride. The combined organic layers were washed with water and then brine, dried over MgSO4, concentrated, and then purified on silica gel column (eluting with 20-50% EtOAc in hexanes) to give the desired product (0.3 g, 59%). LCMS calculated for C12H21NO3Na (M+Na)+: m/z=250.2. Found: 250.1.
