Abstract: A method for enzymatic preparation of fludarabine phosphate, comprising reaction of fludarabine with a high-energy phosphate compound under the action of deoxyribonucleic acid kinase. According to said method, acetate kinase and acetyl phosphate free acid or acetyl phosphate are also added.
