HCID 12084308HCID 12084308, compound

Procedure

A solution of 50% aqueous hydrogen peroxide is added slowly to a mixture of 4-benzoyloxy-1-oxyl-2,2,6,6-tetramethylpiperidine and ferrous chloride tetrahydrate in tert-butyl alcohol at 30-60° C. Excess peroxide is decomposed by aqueous sodium sulfite solution. The organic layer is concentrated and the residue is purified by flash chromatography to afford the title compound.
