Abstract: L-LYSINEAMIDE DIHYDROCHLORIDE CAN BE ISOLATED BY PREPARING THE INTERMEDIATE D- AND L-LYSINEAMIDE-L-PYRROLIDONE CARBOXYLATE HYDROCHLORIDE SALTS WHICH CAN BE SEPARATED FROM ALKANOL SOLUTION BY FRACTIONAL CRYSTALLIZATION. THE L-LYSINEAMIDE PYRROLIDONE CARBOXYLATE HYDROCHLORIDE SALT IS THEN TREATED WITH EXCESS HYDROGEN CHLORIDE TO FORM THE DESIRED L-LYSINEAMIDE DIHYDROCHLORIDE.
