To a stirred solution of 2-{[1-methyl-2-(methoxy)ethyl]oxy}-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (7.2 g, 23.4 mmol) in dichloromethane (100 ml) was added NBS (4.6 g, 25.8 mmol). After 4 h, the solvent was removed. The product was purified on a silica column using petroleum ether: ethyl acetate 2:1 as eluent. This gave the product (7.3 g, 81.1%).
