실험 절차
To a stirred solution of [(R)-1-hydroxymethyl-3-(4-hydroxy-phenyl)-1-methyl-propyl]-carbamic acid tert-butyl ester (1.98 g, 5.03 mMol) in CH2Cl2 (20 ml) is added N-morpholine-N-oxide (884 mg, 7.54 mMol) and tetra-n-propylammonium perruthenate (177 mg, 0.50 mMol). The mixture is stirred at RT for 1 hour. The mixture is then filtered over a short pad of SiO2 eluting with diethyl ether. The filtrate is concentrated under reduced pressure to give the title compound. The crude product is sufficiently pure to be used in the next stage without further purification.
