Reaction Steps

With reference to the first step in scheme 7 above, asiatic acid (5 g) was dissolved in pyridine (10 ml) with stirring. The solution was cooled down to 10° C., and 15 ml of acetic anhydride were added. The resultant solution was stirred at room temperature for 20 hours, and then 200 ml of ice water were added. A precipitate formed, was filtered out and washed with water, and then was dried under 50° C. to yield 6.28 g of asiatic acid triacetate as a white powder.
