반응 단계
750 parts of 4-benzoylamino-1,2,2,6,6-pentamethyl piperidine are dissolved in 1000 parts of concentrated hydrochloric acid and the resulting solution is boiled under reflux for 10 hours. After cooling, sodium hydroxide is added until an alkaline reaction is obtained and the mixture is repeatedly extracted with methylene chloride. The residue obtained after removal of the methylene chloride by evaporation is distilled in vacuo, 300 parts of 1,2,2,6,6-pentamethyl-4-aminopiperidine boiling at 98° C./15 Torr distilling over.
