Versuchsvorschrift

9-(1-Hydroxy-2-propyl)-6-chloropurine (I, 1.5 g, 7 mmol) was added to hydroiodic acid (15 ml) at -10° with stirring for 45 min. The precipitate was filtered, neutralized with anhydrous sodium acetate at 5°, and washed with a little cold water (3 times). Recrystallization from ethanol/H2O, gave colorless crystals. Yield=0.9 g (42%); mp=193°-194°; uv λmax 276 nm (H2O, pH 5.5).
