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 (84.6 mg, 0.139 mmol) was dissolved in TFA (0.5 mL) and DCM (1.0 mL) and the reaction was stirred at room temperature for 1 hour. The reaction mixture was then evaporated to an oil, 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.
