Versuchsvorschrift

200 ml of 50% aqueous sodium hydroxide solution and 1 g of triethylbenzylammonium chloride are added to a solution of 12.8 g of p-chlorophenol in 100 ml of CH2Cl2 ; 16.2 g of 1-methyl-2-(2-chloroethyl)-piperidine are added dropwise, while stirring; and the reaction mixture is stirred for a further one hour. After customary working up, 1-methyl-2-(2-p-chlorophenoxyethyl)-piperidine is obtained. Hydrochloride, m.p. 139°-140°.
