Versuchsvorschrift

The mixture of (R)-4-(6-(4,4-dimethylcyclohexyloxy)naphthalen-2-yl)-4-methyloxazolidin-2-one and lithium hydroxide (45 mg, 0.0019 mol) in ethanol (1.1 mL, 0.019 mol) and water (0.37 mL, 0.021 mol) was heated to reflux for overnight. The crude product was partitioned between ethyl acetate and water and the ethyl acetate layer was concentrated and the crude was brought up in methanol and purified by HPLC. MS: m/z=311.2 [M-NH2]+
