Versuchsvorschrift

N-{[1-(4-Hydroxy-4-phenyl-cyclohexyl)-azetidin-3-ylcarbamoyl]-methyl}-3-trifluoromethyl-benzamide (as prepared in Example 30, 680 mg, 1.43 mmol) in DCM (5 mL) was treated with DAST (Aldrich, 418 μL, 4.29 mmol) dropwise at −78° C. for 4 hours. The reaction was quenched with MeOH, warmed to room temperature and partitioned between DCM and water. The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered, concentrated and the residue was purified by a CombiFlash® system using ethyl acetate and 7N NH3 in MeOH as eluent (from pure ethyl acetate to 5% 7N NH3 in MeOH in ethyl acetate) to afford two title compound as white solid: less polar isomer.
