95 °C

A mixture of 10.1 g (38.6 mmol) of 4-benzoyloxy-2,2,6,6-tetramethylpiperidine, 15.6 g (155 mmol) of 90% aqueous tert-butyl hydroperoxide, 600 mg of molybdenum trioxide and 60 ml of cumene is heated at 95° C. for two hours. The catalyst is removed by filtration and the filtrate is then evaporated at reduced pressure. The residual red oil is chromatographed on silica gel to afford 5.8 g (38% yield) of a white powder, m.p. 105°-108° C.
