Reaction Steps

To a solution of (R)—N—((R)-1-(3-fluoro-4-isopropoxyphenyl)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-2-phenylethyl)-2-methylpropane-2-sulfinamide (398 mg, 0.678 mmol) in MeOH (1.5 mL) was added HCl (1.5 mL, 4 M solution in dioxane) and the reaction mixture was stirred for 30 min. The reaction mixture was diluted with ether (50 mL) and the organic layer was washed with sat. NaHCO3 (20 mL), dried over Na2SO4, filtered and concentrated to give (R)-1-(3-fluoro-4-isopropoxyphenyl)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-2-phenylethanamine as a colorless oil (334 mg, 100% yield). LCMS: RT=1.76 min [M−NH2] 467.24 (Phenomenex Luna C18 column, 4.6×30 mm eluting with 10-90% MeOH/H2O over 2 minutes containing 0.1% TFA; 5 mL/min, monitoring at 220 nm); HPLC: RT=3.04 min, Purity 95% (Phenomenex Luna C18 column, 4.6×50 mm eluting with 10-90% MeOH/H2O over 4 minutes containing 0.2% PPA; 4 mL/min, monitoring at 220 nm) NMR: 400 MHz 1H (CDCl3) 7.15 ppm, 3H, m; 6.99 ppm, 4H, m; 6.89 ppm, 1H, m; 6.84 ppm, 1H, d, J=8.79 Hz; 6.74 ppm, 2H, d, J=6.15 Hz; 5.87 ppm, 1H, m; 4.42 ppm, 1H, m; 3.47 ppm, 2H, s; 1.27 ppm, 6H, dd, J=7.91, 6.15 Hz.
