Procedure

To a stirred solution of {(3aR,4R,6R,6aS)-6-[{6-[(1S)-2,3-dihydro-1H-inden-1-yl-amino]pyrimidin-4-yl}(methyl)amino]-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl}methyl sulfamate (12.0 mg, 0.02 mmol) in methanol (3.00 mL) was added 1.00 M hydrochloric acid (0.10 mL), and the mixture was stirred for 8 h. After quenching by addition of saturated NaHCO3 solution, the resulting mixture was evaporated under vacuum. The residue was purified via silica gel column chromatography eluting with a gradient of 5 to 10% methanol in DCM to afford the title compound (7.80 mg, 71%). 1H-NMR (400 MHz, CD3OD) δ: 8.01 (s, 1H), 7.27-7.13 (m, 4H), 5.67 (s, 1H), 5.42-5.34 (m, 1H), 4.88-4.75 (m, 1H), 4.17 (d, 2H, J=5.6 Hz), 4.04 (dd, 1H, J=8.8, 6.1 Hz), 3.88 (dd, 1H, J=5.8, 4.1 Hz), 3.05-2.96 (m, 1H), 2.89 (s, 3H), 2.93-2.83 (m, 1H), 2.62-2.52 (m, 1H), 2.34-2.24 (m, 1H), 2.01 (dt, 1H, d=13.0, 8.3 Hz), 1.94-1.83 (m, 1H), 1.44 (ddd, 1H, J=13.0, 10.8, 9.1). LC/MS: Rt=5.79 min, ES+ 450.2 (AA Waters).
