Procedure

2.65 parts of acrylonitrile was added dropwise with stirring to a solution of 8.55 parts of 1,2,2,6,6-pentamethylpiperidin-4-ol and 0.30 parts of 40% potassium hydroxide solution in 80 parts of benzene. Stirring was continued at room temperature for 16 hours after which time the solution was washed with water, dried and the benzene solvent removed by distillation under reduced pressure. Fractional distillation of the residue, under reduced pressure gave 1.70 parts of 4-(2'-cyanoethoxy)-1,2,2,6,6-pentamethylpiperidine having a boiling point of 105°-6° C. at 0.1 mm of Hg and the following elemental analysis by weight:
