To a solution of 3-(3-((S)-1-(4-bromophenyl)ethyl)-6-isopropyl-2-oxo-1,3-oxazinan-6-yl)propanoic acid (41 mg, 0.1 mmol) in MeOH (10 mL) was added SOCl2 (5 mL) at 0° C. The reaction mixture was stirred at room temperature for 2 h, concentrated, and purified by preparative TLC to give methyl 3-(3-((S)-1-(4-bromophenyl)ethyl)-6-isopropyl-2-oxo-1,3-oxazinan-6-yl)propanoate (42 mg, 96% yield).
