To a solution of (1R,2S,3R,5R)-3-amino-5-(hydroxymethyl)cyclopentane-1,2-diol.HCl (1.00 g, 5.44 mmol) and 2-amino-4,6-dichloropyrimidine (0.982 g, 5.99 mmol) in isopropyl alcohol (8 mL) was added Et3N (1.90 mL, 13.6 mmol). The reaction was heated to 90° C. for 1 h in an oil bath then cooled, filtered and concentrated in vacuo. The residue was dissolved in CH2Cl2 and purified by flash chromatography (20 to 50% MeOH/CH2Cl2) to afford the title compound as an off-white solid (2.025 g, >99%). LC/MS: Rt=0.81 min ES+ 260 (FA standard).
