Versuchsvorschrift

10.0 g of fludarabine phosphate at a purity of 97.5% is suspended in 100 ml of water within about 5 minutes, and magnesium oxide is added to this solution. The mixture is stirred for one more hour at room temperature and then filtered. The clear solution is poured into 200 ml of acetone, stirred for 1 more hour, and the crystallizate is separated by filtration. 10.0 g (95% of theory) of the fludarabine-phosphate magnesium salt is obtained.
