Reaction Steps

To a suspension of 2-((5-(benzyloxymethyl)-4-chloro-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methylamino)-2-(methylthiomethyl)propane-1,3-diol (9.0 mg, 0.037 mmol) and palladium-black (10 mg) in 7 M methanolic ammonia (2 mL) was added hydrazine hydrochloride (0.250 mL, 6.87 mmol) dropwise. After 1 h at ambient temperature the reaction was virtually complete by TLC (dichloromethane:7 M methanolic ammonia, 3:1, visualised with UV and Erlichs). The supernatant solution was filtered through a small pad of celite and the palladium was washed twice with methanol and also filtered through celite. The combined filtrates were concentrated under reduced pressure and the resulting residue triturated with chloroform and dichloromethane. Lyophilization of the residue gave 2-((4-amino-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methylamino)-2-(methylthiomethyl)propane-1,3-diol (4 mg, 63%) as a white solid. 1H NMR (D2O) δ 8.16 (s, 1H), 7.58 (s, 1H), 4.12 (s, 2H), 3.79-3.70 (m, 4H), 2.85 (s, 2H), 2.15 (s, 3H). +ESMS Found 298.1346 (M+H+) C12H20N5O2S requires 298.1338.
