Methyl bromoacetate was reacted with trimethyla~nine-[~'C] dissolved in methanol, forming the methyl ester of [I4C] labeled betaine hydrobromide. The methyl ester was hydrolyzed in an alkaline medium to (carboxymethy1)trimethylammonium hydroxide inner salt, and then transformed into the hydrochlorid

Abstract
β‐^14^C‐p‐Chloroamphetamine hydrochloride was prepared by condensation of carbonyl‐^14^C‐p‐chlorobenzaldehyde with nitroethane followed by lithium aluminum hydride (LAH) reduation of the resulting chloro‐phenylnitropropene. After purfication the overall yield was about 25%. N‐Methyl‐ and N,N‐dimethyl‐ β‐ ^14^C‐p‐chloroamphetamine were prepared, respectively, by LAH reduction of N‐carbobenzoxy – β‐^14^ C‐ p‐chlorpamphetamine and by reductive (Eschweiler‐Clarke methylation of β‐^14^C‐ p‐ Chlolroamphetamine.
