该中间体在本合成路线中的序号：(IV)The reaction of 14C-labeled acetone (I) with O-benzylhydroxylamine (II) and pyridine in refluxing ethanol gives the corresponding oxime (III), which is methylated with MeLi and BF3.Et2O in toluene to yield labeled N-tert-butyl-O-benzylhydroxylamine (IV). The deprotection of (IV) by hydrogenation with H2 over Pd/C in methanol affords N-tert-butylhydroxylamine (V), which is finally condensed with benzaldehyde 2,4-disulfonic acid sodium salt (VI) in HOAc/water to give rise to the target imine oxide.
