1. (R)-4-phenyl-2-oxazolidinone (16.3 g, 1.0 eq.) was dissolved in 180 mL of dichloromethane and cooled to 0 °C in an ice bath.
2. Triethylamine (15.2 g, 1.5 eq.) and 4-dimethylaminopyridine (DMAP) (366 mg, 0.03 eq.) were added sequentially with stirring.
3. Propionyl chloride (9.2 g, 1.0 eq.) was added slowly and dropwise, keeping the reaction temperature at 0 °C and continuing to stir for 1 hour.
4. Upon completion of the reaction, the reaction mixture was diluted with methylene chloride and washed sequentially with water and saturated sodium bicarbonate solution.
5. Separate the organic phase and dry with anhydrous sodium sulfate.
6. The solvent was removed by depressurized evaporation to obtain the crude product.
7. The crude product was purified by column chromatography to afford the target compound R-4-phenyl-3-propionyl-2-oxazolidinone (III-a) (20.1 g, 92% yield). | [References]
