Procedure

2-(2-Methoxy-ethoxy)-9H-purin-6-ylamine (1 g, 4.78 mmol) (1), α,α′-dibromo-m-xylene (2.52 g, 9.56 mmol) and anhydrous potassium carbonate (1.32 g, 9.56 mmol) were combined in DMF (10 mL) and stirred at ambient temperature for 5 hours. The reaction mixture was diluted with ethyl acetate (120 mL), washed with water (2×), brine, dried with Na2SO4, and evaporated under vacuum. The crude product was purified by chromatography on silica gel with 0-10% methanol in ethyl acetate as eluent. Evaporation of the appropriate fractions gave 9-(3-Bromomethyl-benzyl)-2-(2-methoxy-ethoxy)-9H-purin-6-ylamine (2) (1.1 g, 2.80 mmol, 59%). MS: 392/394 (MH+).
