Reaction Steps
A solution of 4-hydroxy-4-(3-methylsulfanyl-phenyl)-cyclohexanone (as prepared in the previous step, 1.10 g, 4.66 mmol) in THF (10 mL) was treated with Burgess' reagent (1.20 g, 5.00 mmol) at room temperature overnight. The solvent was removed and the residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered, concentrated to give a white solid. To this white solid in MeOH (5 mL) and water (5 mL) was added OXONE (Aldrich, 6.10 g, 10 mmol) at room temperature. The reaction mixture was stirred overnight and quenched with saturated NaHCO3. The solvent was removed in vacuo and the residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered, concentrated and purified by silica gel column on a CombiFlash® system using hexanes and ethyl acetate (from 10% ethyl acetate to 100% ethyl acetate) to afford the title compound as a white solid.
