실험 절차

To a solution of 58 ml of thionyl chloride in 250 ml of chloroform, there is added dropwise a solution of 45 g (0.39 mole) of 4-hydroxymethylpiperidine in 200 ml of chloroform. After stirring for 1 hour under reflux, the reaction mixture is evaporated in a vacuum and the residue is triturated with diethyl ether. There are obtained 54.2 g of 4-chloromethylpiperidine hydrochloride (88% of theory); m.p. 130°-132° C.
