21.1 g of 1,2,3,6-tetramethyl-2,6-diethyl-4-hydroxypiperidine and 20 g of triethylamine are dissolved in 250 ml of dioxane. By addition of 10.9 g of trimethylchlorosilane and using the same procedure of reaction and isolation as described in the previous examples there is obtained 1,2,3,6-tetramethyl-2,6-diethyl-4-(trimethylsiloxy)-piperidine (Compound No. 6), b.p. 78°-79° C./0.35 mm Hg.
