Reaction Steps

To a mixture of 6-pentyl-6,9-dihydro-5H-[1,2,4]triazolo[3,4-i]purin-5-one (0.12 g, 0.487 mmol) in THF (5 mL) in a microwave reaction tube was added N-bromosuccinimide (0.20 g, 1.1 mmol). The mixture was heated at 70° C. in microwave oven for 12 min. After cooling down to room temperature, it was purified using preparative LCMS to provide the product (0.011 g). LCMS calculated for C11H14BrN6O (M+H): 325.0, 327.0. found: 325.0, 327.0.
