(R)-3-(Benzyl((4-hydroxy-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methyl)amino)propane-1,2-diol (0.1 g, 0.305 mmol) was dissolved in hot water (20 ml), cooled to rt and 10% Pd—C (50 mg) added. Hydrogen was added from a balloon and the mixture stirred at rt. After 4 h tlc (CH2Cl2-MeOH-cNH3, 5:4.5:0.5) showed reaction over. The hydrogen was replaced with Ar and the mixture heated to 80° C. to ensure product was in solution then the mixture filtered through Celite and the solvent evaporated to give (R)-3-((4-hydroxy-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methylamino)propane-1,2-diol as a colourless solid (0.072 g, 99%). The product was converted to its hydrochloride salt with 5% HCl. 1H NMR (D2O+DCl, 300 MHz), δ ppm, 9.07 (s, 1H), 7.91 (s, 1H), 4.53 (s, 2H), 4.06 (m, 1H), 3.69-3.57 (m, 2H), 3.33 (dd, 1H, J 12.9, 2.9 Hz), 3.17 (dd, 1H, J 12.9, 9.8 Hz). 13C NMR (D2O+DCl, 75.5 MHz), δ ppm, 153.8 (C), 146.1 (CH), 134.1 (C), 133.1 (CH), 119.6 (C), 104.1 (C), 68.5 (CH), 64.5 (CH2), 50.2 (CH2), 41.8 (CH2).
