Procedure

To a stirred solution of 4-(2,6-dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-bicyclo[2.2.2]octane-1-carbaldehyde (1.6 g, 4.3 mmol) in MeOH (30 ml) was added hydroxylamine hydrochloride (1.2 eq, 5.16 mmol, 356 mg) and a solution of NaOAc (trihydrate, 1.5 eq, 6.45 mmol, 890 mg) in water (10 ml). The resulting mixture was stirred at rt overnight might. The mixture was concentrated in vacuo and the solid residue was suspended in water (15 ml), collected, washed with water and dried to afford a white powder (1.4 g, 84%).
