実験手順

To a slurry of tert-butyl-4-({[4-(2-butynyloxy)phenyl]sulfanyl}methyl)-4-[(hydroxyamino)carbonyl]-1-piperidinecarboxylate (0.24 g, 0.55 mmol) at 0° C. in 7 mL of MeOH was added dropwise 3.5 mL of 30% hydrogen peroxide. The reaction was allowed to warm to room temperature and stirred for 18 h. The reaction was cooled to 0° C. and quenched with 3.5 mL of a saturated solution of Na2SO3. The organics were removed and the aqueous solution was extracted with CH2Cl2. The organics were washed with H2O, brine, dried over MgSO4, filtered and concentrated in vacuo. The residue was triturated with ether to provide 0.166 g (67%) of the desired product as an off white solid. Electrospray Mass Spec: 451.3 (M+H)+
