Reaction Steps

(S)—N—((S)-2-amino-1-(3-bromo-5-fluorophenyl)ethyl)-2-methylpropane-2-sulfinamide (100 mg, 0.297 mmol) was dissolved in DCM (988 μl), followed by pyridine (71.9 μl, 0.890 mmol) and acetic anhydride (28.0 μl, 0.297 mmol). The reaction mixture was stirred at room temperature for 1 h, extracted by EtOAc, washed by water and brine, dried over Na2SO4and concentrated. The residue was dissolved in Et2O (1 mL), then HCl (4 M in dioxane) (148 μl, 0.593 mmol) was added. The reaction mixture was stirred at room temperature for 30 min. After the solvent was decant out, the residue solid was used in next step reaction without purification. LCMS (m/z): 275.1/277.1 (MH+), 0.41 min.
