9-(5-Chloropentyl)-2-{[(1S)-1-methylbutyl]oxy}-8-(methyloxy)-9H-purin-6-amine (80 mg, 0.225 mmol), triethylamine (0.031 ml, 0.225 mmol) and piperidine (0.045 ml, 0.45 mmol) were suspended in DMF (3 ml) and the mixture heated to 70° C. for 18 hours. The solvent was removed and the residue partitioned between DCM (4 ml) and saturated sodium bicarbonate (4 ml). The aqueous phase was re-extracted with further DCM and the combined organic extracts were concentrated and the residue dissolved in 1:1 MeOH:DMSO (1 ml) and purified by MDAP (Method A). The product-containing fractions were combined and evaporated under a stream of nitrogen to give the title compound (47.2 mg).
