A solution of 2-amino-4-benzyloxy-5-N-benzyloxymethylpyrrolo[3,2-d]pyrimidine (1.0 g) in methylene chloride (30 mL) was stirred in an ice bath while N-bromosuccinimide (0.5 g) was added portion-wise. The solution was concentrated and chromatography afforded 2-amino-4-benzyloxy-5-N-benzyloxymethyl-7-bromopyrrolo[3,2-d]pyrimidine (1.15 g) as a white solid. 13C NMR (CDCl3) δ 158.8, 157.2, 150.9, 137.3, 136.6, 131.8, 129.0, 128.8, 128.6, 128.5, 128.3, 127.9, 111.3, 90.3, 77.8, 70.7, 68.4.
