実験手順

To a solution of 1.82 g (3.7 mmol) [(1S,2R,3R,4S)-4-{(1R)-1-[3,5-bis(trifluoromethyl)phenyl]ethoxy}-3-(4-fluorophenyl)cyclohexane-1,2-diyl]dimethanol (step G) in 50 mL methylene chloride cooled to −5° C. in an ice/salt bath was added 1.0 mL (3.5 equiv.) methane-sulfonyl chloride; 2.1 mL (4 equiv.) TEA and 44 mg (0.1 equiv.) DMAP. The reaction mixture was stirred at −5° C. for 30 min then quenched at that temperature by the addition of 20 mL sat. aq. NaHCO3. The mixture was warmed to RT. The organic layer was separated and the aqueous layer extracted with additional 50 mL methylene chloride. The combined organic layer was washed with 20 mL 2N aq. HCl, 30 mL sat. aq. NaHCO3, brine, dried over MgSO4 drying agent, filtered and the solvent evaporated under vacuum to give the title compound as an oil which was used without further purification.
