Reaction Steps

To a solution of (R)—N-((2S,4S)-2-(5-bromo-2-fluorophenyl)-1,5,5,5-tetrafluoro-4-hydroxypentan-2-yl)-2-methylpropane-2-sulfinamide (1.6 g, 3.54 mmol, step 6) in DCM (20 mL)/MeOH (10 mL) was added HCl (4.0M in dioxane; 1.075 ml, 35.4 mmol, Aldrich) at RT. The reaction was stirred for one hour. The reaction was concentrated under reduced pressure and the crude residue was taken up in EtOAc. The solution was washed sequentially with water, saturated aqueous sodium bicarbonate solution, and brine. The organic layer was dried over magnesium sulfate and concentrated under reduced pressure to afford the title compound as yellow oil, used without further purification. MS m/z=347.9 M+. Calculated for C11H11BrF5NO: 348.11
