Procedure

N-Bromosuccinimide (1.152 g, 6.47 mmol) was added to a stirred solution of 2-(cyclobutyloxy)-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (1.248 g, 4.31 mmol) in chloroform (15 ml) at 0° C. The mixture was warmed to room temperature and left overnight when water (15 ml) was added and the phases separated. The aqueous layer was extracted with dichloromethane and the organic extracts were combined, washed with brine, dried over anhydrous magnesium sulphate and evaporated to give the title compound as an orange foam (1.79 g).
