Procedure

A solution of hydrogen chloride in dioxane (4M, 0.71 ml) was added to a solution of 2-{[(1S)-1-methylbutyl]oxy}-8-(methyloxy)-9-[5-(1-piperidinyl)pentyl]-9H-purin-6-amine (0.046 g, 0.126 mmol) in methanol (3 ml). The resultant mixture was allowed to stand overnight at room temperature and then blown down under nitrogen. The residue was dissolved in methanol and loaded onto a 2 g aminopropyl SPE cartridge (pre-conditioned with methanol), eluted with methanol and the resultant solution blown down under nitrogen to give the title compound as a yellow solid (40.97 mg).
