Hydrochloric Acid → HCID 20300870, compound

Participants

Reaction Steps

21.2 g of 3-(p-tert.butyl-phenyl)-1,2-dimethyl-propyl bromide, 17 g of piperidine and 7.5 g of ethyleneglycol are heated to 110° C. for 60 hours. After cooling, the mixture is treated with 2-N hydrochloric acid and the neutral constituent is extracted with ether. Subsequently, the hydrochloric acid solution is made alkaline with 5-N sodium hydroxide solution and extracted with ether. The combined ether extracts are washed neutral with water, dried over sodium sulphate and evaporated. By distillation there is obtained pure 1-[3-(p-tert.butyl-phenyl)-1,2-dimethyl-propyl]-piperidine (boiling point 125° C./0.005 Torr) in the form of a colourless oil.
