    摘要: A process for preparing 3-halogeno-2-hydroxypropyltrimethylammonium halide or especially one having the (S)-configuration, which comprises reacting 2,3-dihydroxypropyltrimethylammonium halide or one having the (S)-configuration, which is obtained by reacting (R)-3-halogeno-1,2-propanediol with trimethylamine, with a halogenating reagent.
    According to the present invention, 3-halogeno-2-hydroxypropyltrimethylammonium halide or one having the (S)-configuration, which is a useful intermediate for the synthesis of camitine or especially (ℓ)-camitine, can be obtained economically, efficiently and easily.
