GENERAL STEPS: In a reaction flask equipped with a mechanical stirrer, a reflux condenser tube, a thermometer, and under nitrogen protection, a solution of (L)-alanine isopropyl ester hydrochloride (Q) (2.8 g, 16.8 mmol) prepared in Example 1 was added with methylene chloride (21 mL). The mixture was stirred at room temperature until a homogeneous suspension was formed. Subsequently, the mixture was cooled to -65°C to -55°C using a dry ice-acetone bath and triethylamine (3.9 g, 38.8 mmol) was added slowly, ensuring that the temperature was maintained below -50°C. The mixture was then cooled to -65°C to -55°C using a dry ice-acetone bath. After addition, cooling was continued to -65°C to -55°C and a solution of dichloromethane (11 mL) of phenyl dichlorophosphate (3.3 g, 15.6 mmol) was added dropwise, controlling the temperature to below -50°C. The reaction mixture was stirred at -65°C to -55°C until the reaction was complete (about 1 h). In another reaction flask equipped with the same apparatus, pentafluorophenol (2.4 g, 13.0 mmol) and dichloromethane (28 mL) were added. The mixture was cooled to 0°C to 5°C and triethylamine (1.6 g, 15.8 mmol) was added slowly, keeping the temperature below 10°C. After the addition, the temperature was raised to 20°C to 25°C and maintained for 1 h. It was then added to the previously prepared mixture, which had to be cooled down to -15°C to -10°C and ensuring that the internal temperature did not exceed 5°C. After the addition, the reaction mixture was After addition, the reaction mixture is warmed to 0°C to 5°C and maintained until the reaction is complete (about 1 hour). Water (8.7 mL) was added to the reaction system and the temperature was controlled to be below 10°C. The reaction was then warmed to 20°C to 25°C, partitioned, and the organic phase was washed with water and concentrated to dryness under reduced pressure. The residual solvent was removed by azeotropic isopropyl acetate to give 9.0 g of residue (quantitative yield) with diastereoisomer ratio Sp:flp = 50:50.
