9-[4-Hydroxy-2-(hydroxymethyl)butyl]guanine (46 mg; Example 1) was dissolved in 0.4 ml of 1M aqueous hydrochloric acid and the solution was lyophilized (0.1 mm Hg) over-night. The residue (53 mg, quantitive yield) was dissolved in a few drops of warm ethanol and precipitated with several volumes of tetrahydrofuran to yield a white, crystalline product. M.p. ~85° C. (d).
