To a solution of tert-butyl (aminosulfonyl)({(1S,2S,4R)-2-hydroxy-4-[(6-{[(1R,2S)-2-methoxy-2,3-dihydro-1H-inden-1-yl]amino}pyrimidin-4-yl)oxy]cyclopentyl}-methyl)carbamate (34.5 mg, 0.0000628 mol) in CH2Cl2 (1.4 mL) was added trifluoroacetic acid (0.70 mL, 0.0091 mol) and the mixture was stirred for 15 minutes. The mixture was diluted with toluene and evaporated to dryness. The residue was purified by flash chromatography (0 to 10% MeOH/CH2Cl2) to obtain 23.8 mg (84%) of the title compound as a white residue. 1H NMR (CD3OD, 400 MHz) δ: 8.15 (s, 1H), 7.24-7.14 (m, 4H), 5.98 (s, 1H), 5.57 (bs, 1H), 5.29 (bs, 1H), 4.38-4.35 (m, 1H), 4.23-4.20 (m, 1H), 3.34 (s, 3H), 3.25-3.20 (m, 1H), 3.13-3.00 (m, 3H), 2.42-2.33 (m, 1Hi), 2.29-2.24 (m, 1H), 2.10-1.94 (m, 3H) ppm. LC/MS: Rt=1.16 min, ES+ 450 (FA standard).
