Reaction Steps

A mixture of 17.23 g (0.10 mol) of 1-oxyl-4-hydroxy-2,2,6,6-tetramethylpiperidine and 106.17 g (1.0 mol) of ethylbenzene under a nitrogen atmosphere is heated at 133° C. for 26 hours. The volatiles are removed in vacuo and the residue is triturated with diethyl ether. The precipitate of 1,4-dihydroxy-2,2,6,6-tetramethylpiperidine is collected by filtration to give 12.57 g of an off-white solid.
