2-iodo-1,1,1-trifluoroethane (12.5 μl, 0.127 mmol) was added to a stirred solution of (3R,3aR,6R,6aR)-6-[1-allyl-6-chloro-5-[4-(5,6-dihydro-4H-pyrrolo[3,4-c]pyrazol-2-yl)phenyl]imidazo[4,5-b]pyridin-2-yl]oxy-2,3,3a,5,6,6a-hexahydrofuro[3,2-b]furan-3-ol (59.9 mg, 0.115 mmol) in dioxane (0.46 ml). The reaction mixture was a pale yellow solution that was heated to 80° C. After 2 days, N,N-diisopropylethylamine (40 μl, 0.229 mmol), 2,2,2-trifluoroethyl trifluoromethane-sulfonate (34 μl, 0.236 mmol), and additional dioxane (0.2 ml) were added to the reaction mixture. After stirring an additional 18 hours, the reaction mixture was cooled to room temperature. The reaction mixture was evaporated under reduced pressure to give a dark amber residue. The residue was 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 followed by a 80% acetonitrile/water+0.05% TFA flush. The product fractions were combined and evaporated under reduced pressure to give the desired product as an amber residue.
