Procedure

4-(2-amino-6-chloropurin-9-yl)methyl-1,3-dioxane (prepared according to Example 5) was dissolved in hydrochloric acid (1 mol/l) and refluxed for four hours. The solution was made alkaline with diluted ammonium hydroxide and evaporated to dryness at reduced pressure. The residue was dissolved in water and purified with preparative HPLC on a reversed phase column (μ Bondapack C18)eluted with a mixture of methanol and water (1:3). The product obtained was a white crystalline solid. M.p. 226°-8° C. (dec) (uncorrected) UV spectra (hydrochloric acid 0.01 mol/l): λmax (nm) 277, 254 (ε=10700).
