Reaction Steps

To a stirred solution of 1-[4-(4-chloro-benzenesulfonyl)-4-(2,5-difluoro-phenyl)-cyclohexylmethanesulfonyl]-azetidin-3-ol (Example 30) (143 mg, 0.28 mmol.) in dichloromethane (10 mL) was added Dess-Martin periodinane (230 mg, 0.56 mmol.) and the mixture stirred at ambient temperature for 18 hours. Ethyl acetate (20 mL) was added and the solution washed with 10% sodium thiosulfate solution (20 mL), water (20 mL) and brine (20 mL), dried (MgSO4) and evaporated to leave a residue which was purified by column chromatography on silica, eluting with ethyl acetate:dichloromethane:iso-hexane (1:1:2), to afford the desired product (98 mg).
