摘要
A process for manufacturing the D camphorate of L carnitinamide and the D camphorate of D carnitinamide is disclosed, wherein D,L carnitinamide hydrochloride is converted to D,L carnitinamide free base which directly reacts with D camphoric acid either as an aqueous suspension or in solid form, thus obtaining a solution of D camphorate of D,L carnitinamide. The resolution of the optical isomers is achieved by drying this solution and taking up the residue with isopropanol, whereupon the D camphorate of L carnitinamdide crystallizes out of the isopropanol solution and the D camphorate of D carnitinamide remains in solution.
