Reaction Steps

A solution of (2R,3S)-2-(((5-(benzyloxymethyl)-4-chloro-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methyl)(methyl)amino)-4-(methylthio)butane-1,3-diol (240 mg, 0.5 mmol) in 7N NH3 in MeOH (5 ml) was heated in a sealed tube at 140 C (bath temp) overnight. The reaction was concentrated in vacuo and the resulting residue purified by flash chromatography on silica gel eluting with 10%. MeOH/DCM=>10% 7 N NH3 to afford (2R,3S)-2-(((4-amino-5-(benzyloxymethyl)-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methyl)(methyl)amino)-4-(methylthio)butane-1,3-diol (120 mg, 52%) as a syrup. 1H NMR (CD3OD) δ 8.16 (s, 1H), 7.41 (s, 1H), 7.27 (m, 5H), 5.60 (s, 2H), 4.57 (s, 2H), 4.07 (d, J=15.0 Hz, 1H), 3.82 (m, 3H), 3.71 (dd, J=12.0, 6.0 Hz, 1H), 2.88 (m, 1H), 2.77 (dd, J=15.0, 3.0 Hz, 1H), 2.54 (dd, J=15.0, 6.0 Hz, 1H), 2.43 (s, 3H), 2.03 (s, 3H). 13C NMR (CD3OD) δ 153.2, 151.8, 150.4, 138.2, 134.4, 130.0, 129.7, 129.6, 116.8, 115.3, 79.0, 71.8, 70.8, 67.0, 60.2, 50.0, 40.2, 39.1, 16.8.
