To a round bottom flask containing (S)-tert-butyl(1-(2-fluoro-4-(2-fluoropropan-2-yl)phenyl)ethyl)carbamate (126 mg, 0.42 mmol) was added HCl in dioxane (2.1 mL, 8.42 mmol). Resulting reaction mixture allowed to stir 1 hr at room temperature. Volatiles were removed. Et2O was then added and the mixture sonnicated briefly. Volatiles were once again removed to a afford an HCl salt of (S)-1-(2-fluoro-4-(2-fluoropropan-2-yl)phenyl)ethanamine (104 mg, 0.44 mmol, 105% yield) as a white solid. 1H NMR (400 MHz, D2O) δ 1.59-1.80 (m, 9H) 7.24-7.37 (m, 2H) 7.43-7.56 (m, 1H). LCMS m/z 200.1 (M+H)+, Rt 0.54 min.
