N-Iodosuccinimide (588 mg, 0.00261 mol, Acros) and zirconium tetrachloride (98 mg, 0.00042 mol, Strem) was added to a solution of repurified (R)-4-methyl-4-[6-(trans-4-trifluoromethyl-cyclohexyloxy)-naphthalen-2-yl]-oxazolidin-2-one (786 mg, 0.00200 mol) in methylene chloride (30 mL, Acros) and were stirred at room temperature for 30 min. Silica gel was added and the reaction was evaporated to dryness. The residue was purified by silica gel chromatography using 0-100% ethyl acetate in hexanes as eluent. Cis and trans isomers were fully resolved and isolated was 822 mg (79%) of pure trans product (Rf=0.31 in 1:1 hexanes/ethyl acetate).
