Reaction Conditions

Reaction Steps

A mixture of 20.0 g (0.12 mol) of 1-oxyl-4-hydroxy-2,2,6,6-tetramethylpiperidine and 164.0 g (1.04 mol) of 1-octene is heated under a nitrogen atmosphere at 100° C. for 24 hours, and then for an additional 24 hours at 115° C. The reaction mixture is filtered to remove 1,4-dihydroxy-2,2,6,6-tetramethylpiperidine, and the filtrate is washed with 10% (w/v) ascorbic acid (2×50 mL) and distilled water (2×50 mL). The organic phase is dried over anhydrous magnesium sulfate and the volatiles removed in vacuo. The residue is chromatographed to give 14.4 g (83% yield) of the title compound as an amber oil.
