Participants

Reaction Steps

A mixture of 13.77 g (0.05 mol) of 1-oxyl-4-benzoyloxy-2,2,6,6-tetramethylpiperidine and 106.17 g (1.0 mol) of m-xylene under a nitrogen atmosphere is heated at reflux for 50 hours. The reaction mixture is filtered to remove the hydroxylamine, and the filtrate is washed with 10 w/v % ascorbic acid (1×50 mL) and distilled water (2×50 mL). The organic phase is dried over anhydrous sodium sulfate and the volatiles are removed in vacuo. The residue is recrystallized from isopropyl alcohol to give 5.62 g (59% yield) of a white solid melting at 64-65° C.
