Procedure
To a solution of (1R,2S,3R,5R)-3-[(6-chloropyrimidin-4-yl)amino]-5-(hydroxymethyl)cyclopentane-1,2-diol (1.880 g, 7.239 mmol) in hydroiodic acid (23.9 mL) was added sodium iodide (5.42 g, 36.2 mmol). The mixture heated to 70° C. for 10 min then concentrated and azeotroped using toluene (3×). The residue was dissolved in acetone and NaHCO3 was added. The suspension was filtered and the filtrate was concentrated in vacuo to obtain the title compound (24 g, >99%). LC/MS: Rt=0.76 min ES+ 352 (FA standard).
