실험 절차

To a solution of (S)-ethyl 2-((S)-1,1-dimethylethylsulfinamido)-4-fluoro-3,3-dimethylbutanoate (0.38 g, 1.350 mmol) in MeOH (10 mL) was added HCl/dioxane (1.350 mL, 5.40 mmol). The reaction mixture was stirred at rt for 30 min and concentrated to afford (S)-ethyl 2-amino-4-fluoro-3,3-dimethylbutanoate/HCl as a white solid (0.29 g).
