실험 절차
(S)-tert-butyl (1-(3-fluoro-5-iodophenyl)-2-hydroxyethyl)carbamate (2.507 g, 6.58 mmol) was dissolved in DCM (60 mL) and treated with 4 N HCl in dioxane (4.93 mL, 19.73 mmol). The mixture was stirred overnight at room temperature. After the majority of the solvent was evaporated carefully in vacuo, the slurry was triturated with Et2O to afford 1.525 g of a fine white HCl salt of (S)-2-amino-2-(3-fluoro-5-iodophenyl)ethanol (72%), which was isolated by suction filtration. LCMS (m/z): 282.4 (MH+), 0.46 min.
