Reaction Conditions

Reaction Steps

To a refluxing mixture of 13.5 g (19.0 mmol) of 2,4,6-tris[N-(2,2,6,6-tetramethylpiperidin-4-yl)-n-butylamino]-1,3,5-triazine, 0.2 g of molybdenum trioxide, and 175 ml of cyclohexane are added 36.6 g (284 mmol) of 70% aqueous t-butyl hydroperoxide over a 10 minute interval. The red reaction mixture is heated at reflux for one hour and then transferred to a Fischer-Porter pressure bottle using 25 ml of fresh cyclohexane. The reaction mixture is then heated for 3 hours at 150° C. to discharge the red color. Solids are removed by filtration and the filtrate is concentrated to a residue which is purified by flash chromatography on silica gel (19:1 heptane:ethyl acetate). The product is crystallized from isopropyl alcohol to afford 7.6 g (40% yield) of a white powder, m.p. 189°-94° C.
