Reaction Steps
There was suspended 9.20 g of 2,3-dihydroxypropyltrimethylammonium chloride (chemical purity: 100%) in 50 ml of dimethylformamide, and thereto 6.80 g of thionyl chloride was added at a temperature from 5° to 10° C. After stirring for 20 minutes, it was heated at 100° C. for 5 hours. Finally, after cooling the reaction mixture to room temperature, 9.85 g of 3-chloro-2-hydroxypropyltrimethylammonium chloride was obtained by evaporating the reaction mixture to dryness.
