162.5 g of the N-(2,2,6,6-tetramethyl-4-piperidylidene)-2-methylallylamine are dissolved in 162 ml of toluene in a 500 ml three-necked flask with reflux condenser, and 4.86 g of potassium tert-butylate are added. To the reaction mixture are then added, with stirring, 50 ml of dimethyl sulfoxide, and stirring is maintained at 50° C. for 8 hours. The organic phase is afterwards extracted with 100 ml of distilled water, and the organic part, after separation of the solvent, is distilled to yield 136.9 g of N-(2,2,6,6-tetramethyl-4-piperidylidene)-2-methyl-1-amino-1-propene as a colourless liquid, b.p. 56° C. at 40 Pa (82% of theory).
