Reaction Steps

To a solution of (S)-tert-butyl 4-(3-(chloromethyl)-5-fluorophenyl)-2,2-dimethyloxazolidine-3-carboxylate (140 mg, 0.407 mmol) in anhyd DCM (1.357 mL) was added 4 N HCl in Dioxane (1.018 mL, 4.07 mmol) portionwise. The mixture was refluxed at 80° C. overnight. The reaction was not completed. More 4N HCl in dioxane (1. 018 mL, 4.07 mmol) was added, and refluxed for another 24 h. Solvent was removed under reduced vacuum to provide (S)-2-amino-2-(3-(chloromethyl)-5-fluorophenyl)ethanol (70 mg, 84%). LCMS (m/z): 204 (MH+), 0.41 min.
