Participants

Reaction Steps

2-(Butyloxy)-8-(methyloxy)-9-{3-[(tetrahydro-3-furanylmethyl)amino]propyl}-9H-purin-6-amine (11 mg, 0.029 mmol) and 4M HCl in 1,4 dioxane (0.160 ml, 0.639 mmol) were stirred at 20° C. for 16 hours in methanol (1 ml). The solvent was removed by N2 blowdown. The sample was loaded in methanol and purified by SPE on an aminopropyl (NH2) cartridge (2 g) using methanol. The appropriate fractions were combined and dried under a stream of nitrogen to give the crude product as a white solid. The sample were dissolved in 1:1 MeOH:DMSO (1 ml) and purified by Mass Directed AutoPrep (Method A). The solvent was dried under a stream of nitrogen in the Radleys blowdown apparatus to give the title compound as a white solid (5.6 mg).
