Reaction Steps

There was added 40 ml of 30 w/v % aqueous solution of trimethylamine to 10.40 g of (R)-3-chloro-1,2-propanediol (optical purity: 100% e.e., chemical purity: 99%). After reacting for 2 hours at room temperature, the reaction mixture was evaporated to dryness to give 15.60 g of (S)-2,3-dihydroxypropyltrimethylammonium chloride as crystals.
