Versuchsvorschrift

6-Amino-9-(2-deoxy-2-fluoro-β-D-ribofuranosyl)-9H-purine (0.29 g, 1.0 mmole), prepared as in Example 8, was dissolved in 100 ml of water. Calf intestinal adenosine deaminase (4 I.U., Boehringer Mannheim) was added and the solution incubated at 37° C. for 24 hrs. The solvent was removed under vacuum. The residue was dissolved in water/n-propanol (7/3) and chromatographed on a 5×90 cm column of Sephadex G-10 (Pharmacia LKB) with water/n-propanol (7/3) as the solvent. Product-containing fractions were combined and the solvent removed under vacuum. The residue was dissolved in water and lyophilized to obtain title compound that analyzed as a hydrate.
