Reaction Steps

Glucosamine hydrochloride (6.45 g, 0.03 mol) and sodium hydrogen sulphate (1.8 g, 0.015 mol) were taken in a flask and dissolved in water (25 ml). The resulting solution was added dropwise to vigorously stirred isopropanol(150 ml) at room temperature over a period of one hour. The contents in the flask were further stirred for 4 hrs and then kept at 0° C.-5° C. for 16 hrs. The precipitate was filtered under vacuum (150 mm Hg). The product was washed twice (each time with 25 ml of isopropanol).
