A solution of 3-bromopentane was prepared by dissolving 1 mmole in acetonitrile (1 ml). A portion of this solution (0.12 ml, equivalent to 0.12 mmol) was added to a test tube. 2-(Butyloxy)-8-(methyloxy)-9-[2-(3-piperidinyl)ethyl]-9H-purin-6-amine (435 mg, 1.2 mmol) was dissolved in DMF (6.0 ml) and an aliquot (0.5 ml, 0.1 mmol) dispensed to the tube. DIPEA (40 μL, 0.23 mmol) and potassium carbonate (46 mg, 0.3 mmol) added, and heated to 50° C. for 18 hr. An additional aliquot of 3-bromopentane in acetonitrile (80 uL, 0.08 mmol) (total added 0.2 mmol) and DIPEA (40 uL, 0.23 mmol) was added and continued stirring with heat at 50° C. for a further 18 hours. DMSO:MeOH (200 uL) was added, the mixture filtered and purified by Mass Directed AutoPrep (Method A). The solvent was evaporated in vacuo using the Genevac. The residue was redissolved in a solution of 4M HCl/dioxane (0.2 ml) and allowed to stand at room temperature for 4 hours. The solvent was dried under a stream of nitrogen in the Radleys blowdown apparatus. The material was redissolved in methanol (0.5 ml) and applied to an aminopropyl SPE (0.1 g, 3 ml, preconditioned in methanol (1.5 ml)). The product was eluted with additional methanol (1.5 ml). The solvent was removed to give the title compound (6 mg).
