Procedure

To a solution of 10 g 2-(6-amino-purin-9-yl)ethanol in 200 ml 0.5M AcONa/AcOH buffer pH 4 were added 4 ml of Br2. The resulting mixture was stirred at room temperature for 8 hours. The precipitated product was isolated, washed with water and crystallized from ethanol to give 6.13 g (43%) of the desired compound.
