Reaction Steps

To a 150 mL round-bottomed flask was added (R)-N-((2S,4S)-2-(6-bromo-3-fluoropyridin-2-yl)-1,5,5,5-tetrafluoro-4-hydroxypentan-2-yl)-2-methylpropane-2-sulfinamide (2.01 g, 4.43 mmol), 1,4-dioxane (30 mL) and finally HCl in 1,4-dioxane (Aldrich; 4.43 mL, 17.7 mmol, 4 M). The solution was stirred at rt for 45 min and then poured into sat NaHCO3 (100 mL) and extracted with EtOAc (2×100 mL). The combined extracts were dried (Na2SO4) and concentrated to afford (2S,4S)-4-amino-4-(6-bromo-3-fluoropyridin-2-yl)-1,1,1,5-tetrafluoropentan-2-ol which was carried on directly. MS m/z=351.0 [M+H]+. Calculated for C10H10BrF5N2O: 350.0.
