Procedure
A 100-mL of flask was charged with 2-(3-(2′,4′-difluorobiphenyl-3-yl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)acetic acid (1.02 g, 2.4 mmol) dissolved in MeOH (15 mL). Then thionyl chloride (418 mg, 3.5 mmol) was added dropwise slowly at 0° C. under N2 protection. The mixture was stirred overnight under reflux. The mixture was concentrated to give the crude product, which was purified by chromatography to give the pure product (230 mg, 23%).
