Participants

Reaction Steps

The product from Example 2.5 (0.08 g, 0.206 mmol) was dissolved in 7M NH3-MeOH solution (8 ml) and Pd black (80 mg) added followed by hydrazine hydrate (1.2 ml). The mixture was stirred for 40 mins, filtered and the solvent evaporated. The residue was chromatographed on silica gel (CH2Cl2-7M NH3 in MeOH, 85:15) to give(S)-1-((4-amino-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methylamino)-3-(methylthio)propan-2-ol (0.042 g, 76%) as a colourless solid. [α]D20 −12.4 (c, 0.355, MeOH). 1H NMR (CD3OD), δ 8.16 (s, 1H), 7.48 (s, 1H), 4.00 (d, J=13.5 Hz, 1H), 3.92-3.84 (m, 2H), 2.85 (dd, J=12.2, 3.5 Hz, 1H), 2.65 (dd, J=12.2, 8.5 Hz, 1H), 2.55 (d, J=6.5 Hz, 2H), 2.10 (s, 3H). 13C NMR (CD3OD, referenced to the centre line of CD3OD at 49.0 ppm), δ 152.1, 150.9, 146.6, 129.1, 115.4, 114.2, 70.2, 54.6, 43.5, 40.4, 16.2. +ESMS Found 268.1241 (M+H)+ C11H18N5OS requires 268.1232.
