Procedure
2-[(3aR,6R,6aS)-6-[6-chloro-5-(4-phenylphenyl)-1-(2-trimethylsilylethoxymethyl)-imidazo[4,5-b]pyridin-2-yl]oxy-2,3,3a,5,6,6a-hexahydrofuro[3,2-b]furan-3-yl]acetamide was dissolved in TFA (0.5 mL) and DCM (0.5 mL) and stirred at room temperature for 2 hours. The reaction mixture was evaporated to give an oil. The oil was dissolved in methanol (0.5 mL) and purified by preparative HPLC reverse phase (C-18), using a 30×150 mm Sunfire™ column and eluting with a 20%-80% acetonitrile/water+0.05% TFA gradient. The desired fractions were lyophilized to give the title compound as a solid. Major isomer LC-MS: calculated for C26H23ClN4O4 490.14 observed m/e: 491.23 (M+H)+ (Rt 0.53/2 min); 1H NMR δ (ppm) (CD3OD): 7.94 (s, 1H), 7.76 (ABq, 4H), 7.71 (d, 2H), 7.48 (dd, 2H), 7.38 (dd, 1H), 5.58 (qt, 1H), 5.00 (t, 1H), 4.56 (t, 1H), 4.12 (dd, 1H), 4.02 (m, 2H), 3.54 (dd, 1H), 2.64 (dd, 1H), 2.58 (m, 1H) and 2.38 (dd, 1H).
