62.7 g of 4-hexyloxy-2,2,6,6-tetramethylpiperidine are added with stirring to a solution of 23.9 g of cyanuric chloride in 100 ml of toluene. The mixture is subsequently heated to 80° for 24 hours. A white precipitate of the piperidine hydrochloride is formed during this. After cooling, the precipitate is filtered off, and the toluene solution is washed a number of times using 2N hydrochloric acid, dried over Na2SO4 and evaporated. The residue is recrystallized from acetonitrile. The product obtained melts at 49°-51°.
