Reaction Steps

A mixture of 9.87 parts of 4-allyloxy-2,2,6,6-tetramethylpiperidine and 3.03 parts of allyl bromide was heated at 90° C. for 96 hours. Ether was added to the cooled reaction mixture and the 4-allyloxy-2,2,6,6-tetramethylpiperidine hydrobromide formed during the reaction was filtered off. The ether solvent was removed by distillation under reduced pressure and the residue purified by chromatography to give 4-allyloxy-1-allyl-2,2,6,6-tetramethylpiperidine.
