Versuchsvorschrift

36.7 g of 2,6-diethyl-2,3,6-trimethylpiperidine (Compound No. 1) are dissolved in 200 ml toluene. A solution of 19 g acrylic chloride in 50 ml toluene is added slowly within an hour and the mixture is stirred at 70°-75° C. for 18 hours. After addition of 21.2 g of triethylamine the stirring is continued for another 24 hours. After cooling the reaction mixture is washed twice with 100 ml water each. The toluene solution is dried over sodium sulfate and evaporated. The residue is distilled in vacuo and there is obtained the 1-acryloyl-2,6-diethyl-2,3,6-trimethylpiperidine (Compound No. 12) as distillate at 133°-135° C./0.6 mm Hg.
