(R)-4-[6-(4-tert-Butyl-cyclohexyloxy)-5-cyclopropyl-naphthalen-2-yl]-4-methyl-oxazolidin-2-one (0.1093 g, 0.0002593 mol) was dissolved in ethanol (2.00 mL, 0.0342 mol) in a capped 40 mL vial equipped with a magnetic stir bar. 4.2 M lithium hydroxide, monohydrate in water (1.00 mL, 0.00420 mol) was added and the reaction was stirred overnight at 80° C. HPLC analysis showed that the reaction was complete. The solvent was removed under reduced pressure. Methylene chloride and water were added and the layers were separated. The combined organic layer was concentrated to dryness and purified by HPLC to give 41.0 mg of the title compound (40% yield).
