Procedure

9-[3-(1-Azetidinyl)propyl]-2-(butyloxy)-8-(methyloxy)-9H-purin-6-amine (13 mg, 0.039 mmol) was dissolved in methanol (3 ml) and 4M hydrogen chloride in 1,4-dioxane (0.243 ml, 0.972 mmol) was added and the mixture stirred at room temperature for 18 hours. The solvent was removed in vacuo and the residue was dissolved in methanol and loaded onto an aminopropyl SPE cartridge (2 g). The cartridge was eluted with methanol and the solvent removed to give the title compound as a white solid (13 mg).
