Abstract
A process for the preparation of 2-p-chlorophenyl-1,5,5-trimethyl-4-methylenepiperidine of formula (I) and its addition salts with pharmacologically acceptable acids, for example the hydrochloride ** (formula) ** characterized in that the hydrochloride of 3,3-dimethyl-4-methylamino-2-butanone is reacted with p-chlorobenzaldehyde in the presence of p-toluenesulfonic acid, whereby 2-p-chlorophenyl-1,5,5 is obtained -trimethyl-4-piperidone.
