Aminoacid hydrochlorides or diaminoacid dihydrochlorides are produced by first reacting a halocarboxylic acid ester with an alkali metal cyanate in the presence of an alcohol to form the corresponding mono- or diurethane and then saponifying this to the corresponding mono- or dihydrochloride. The new process is relatively versatile in its use and above all opens up an elegant synthesis route for lysine.
