반응 단계

To a mixture of 3-((S)-1-(4-bromophenyl)ethyl)-6-(3-hydroxypropyl)-6-isopropyl-1,3-oxazinan-2-one. (41 mg, 0.1 mmol) in acetone (10 mL) was added Jones reagent (2.5 M, 1 mL) at 0° C. The mixture was stirred at room temperature for 1 h, concentrated, and extracted with EtOAc. The organic layer was concentrated to give the crude product 3-(3-((S)-1-(4-bromophenyl)ethyl)-6-isopropyl-2-oxo-1,3-oxazinan-6-yl)propanoic acid (51 mg, 95% yield), which was used for the next step without further purification.
