Reaction Steps

(R)-4-methyl-4-(6-(4-pentylcyclohexyloxy)naphthalen-2-yl)oxazolidin-2-one (0.3672 g, 0.0009284 mol) was dissolved in ethanol (5.00 mL, 0.0856 mol) in a capped 40 mL EPA vial equipped with a stir bar. 4.2 M Lithium hydroxide, monohydrate in water (2.00 mL) was added and the mixture was heated at 80° C. overnight. TLC analysis showed that the reaction was complete. The mixture was concentrated to dryness under vacuum. The product was dissolved in methylene chloride (5 mL) and washed with water (2×5 mL). The layers were separated (phase separator cartridge) and the organic layer was concentrated to dryness and purified by HPLC to give 0.467 g of the title compound (14% yield).
