(R)-N-((S,Z)-2-(5-bromo-2-fluoropyridin-3-yl)-4-(2,2-dimethylhydrazono)-1,5,5,5-tetrafluoropentan-2-yl)-2-methylpropane-2-sulfinamide (0.510 g, 1.034 mmol) was dissolved in THF 5 mL. Hydrochloric acid 1N solution (1.034 ml, 1.034 mmol) was added dropwise. The reaction mixture was stirred at room temperature overnight and worked up with saturated aqueous NaHCO3 and extracted with EtOAc three times. The combined organic layers were washed with brine, dried on sodium sulfate, filtered and concentrated. The crude material was purified by column chromatography using a gradient of 15-50% EtOAc/hexane to give (R)-N-((S)-2-(5-bromo-2-fluoropyridin-3-yl)-1,5,5,5-tetrafluoro-4-oxopentan-2-yl)-2-methylpropane-2-sulfinamide (0.356 g, 0.789 mmol, 76% yield). MS m/z=490.9 [M+CH3CN]+. Calculated for C14H16BrF5N2O2S: 451.250.
