Procedure

tert-Butyl cis-3-fluoro-4-((4-(N-isobutyl-N-(5-isopropyl-3-methylpyridin-2-yl)sulfamoyl)phenoxy)methyl)piperidine-1-carboxylate (53 mg, 0.09 mmol) was dissolved in trifluoroacetic acid (TFA) (1 mL) and dichloromethane (DCM) (1 mL) and stirred under nitrogen, at room temperature for 30 minutes. The reaction was concentrated under a stream of nitrogen, then purified by mass directed autoprep (ammonium carbonate modifier) to give the title compound (22 mg). LCMS (2 min, formic) Rt 1.06 min, m/z (ES+) 478 (M+H).
