Procedure

With stirring, 35 g (0.1 mole) of benzil-di-(2-chloroethyl)ketal and 77 g (0.9 mole) of piperidine are kept for 7 hours at 105° C. After cooling, the reaction mixture is diluted with ether and the piperidine hydrochloride is collected by filtration. The ether is distilled off and the residual oil is dried in a high vacuum.
