Procedure

A solution of {(1S,2S,4R)-2-{[tert-butyl(dimethyl)silyl]oxy}-4-[(2-{[(1S)-5-chloro-3,3-dimethyl-2,3-dihydro-1H-inden-1-yl]amino}pyridin-4-yl)oxy]cyclopentyl}methyl sulfamate (0.0287 g, 0.0000481 mol) in 3.0% (V/V) HCl in ethanol (25.0 ml) was stirred for 4 hrs. The reaction was concentrated and dissolved in 50 ml EtOAc and 1.00 ml triethylamine. The solution was washed with water, concentrated, and the residue was isolated by preparative plate chromatography (5% MeOH/EtOAc) to afford the title compound (16.5 mg, 71%) as a white solid. 1H NMR (CDCl3, 400 MHz) δ: 7.92 (d, 1H, J=5.8 Hz), 7.22-7.20 (m, 1H), 7.17-7.14 (m, 2H), 6.16 (dd, 1H, J=6.0 Hz, J=2.3 Hz) 5.85 (d, 1H, J=2.0 Hz), 5.30 (m, 1H), 4.92 (m, 1H), 4.70 (d, 1H, J=8.5 Hz), 4.50 (dt, 1H, J=5.0 Hz, J=1.9 Hz), 4.40 (dd, 1H, J=7.3 Hz, J=2.5Hz), 4.28 (dd, 1H, J=7.3 Hz, J=2.5 Hz), 2.60 (bs, 1H), 2.50 (q, 1H, J=7.0 Hz), 2.31-2.25 (m, 1H), 2.18-2.12 (m, 1H), 1.95-1.87 (m, 2H), 1.79 (m, 1H), 1.25 (s, 6H). LC/MS: Rt=1.81 min, ES+ 482 (AA standard).
