To a solution of (R)—N—((R)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)-2-methylpropane-2-sulfinamide (38 mg, 0.081 mmol) in methanol (0.2 mL) was added 4N HCl in dioxane (0.2 mL). The resulting reaction was stirred at room temperature for 5 minutes and the solvent was evaporated under reduced pressure. The crude product was diluted in EtOAc and washed with sat'd. NaHCO3 and dried over Na2SO4. The EtOAc was evaporated under reduced pressure and pumped to dryness to afford (R)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethanamine (26 mg, 92% yield) as a colorless oil. LC-MS (ESI) 345.17 (M+H−17), 362.19 (M+H), retention time=3.26 minutes (0-100% MeOH/H2O/0.1% TFA, 4 min run).
