实验步骤: To thionyl chloride (7.7 g, 64.7 mmol), 2-chlorophenylacetic acid (10 g, 58.6 mmol) was added. The mixture was stirred at 50° C. for 3 hours. After stirring, sulfuryl chloride (12.7 g, 93.8 mmol) was added thereto at the same temperature for reaction overnight. After the reaction, toluene (45 mL) was added and (2R)-1-oxo-1-pyrrolidinylpropane-2-ol (9.2 g, 64.5 mmol) was added thereto at the same temperature. Subsequently, triethylamine (7.7 g, 93.8 mmol) was added to carry out reaction for 2 hours. After the reaction, water was added thereto and the water layer was disposed of. The obtained organic layer was washed with water, and the water layer was disposed of. The organic layer was concentrated under reduced pressure to obtain 19 g of the concentrate of the target compound. After stirring at the same temperature for reaction overnight was added reaction for 2 hours was added The obtained organic layer was washed with water The organic layer was concentrated under reduced pressure to obtain 19 g of the concentrate of the target compound

实验步骤: To phosphorus tribromide (28 g, 103.4 mmol), 2-chlorophenylacetic acid (44 g, 257.9 mmol) was added. The mixture was stirred at 50° C. for 1 hour. After stirring, bromine (66 g, 413.0 mmol) was added thereto at the same temperature for reaction overnight. After the reaction, toluene (200 mL) and (2R)-1-oxo-1-pyrrolidinylpropane-2-ol (40.6 g, 283.6 mmol) were added thereto at the same temperature. Subsequently, triethylamine (34 g, 336.0 mmol) was added thereto to carry out reaction for 2 hours. After the reaction, water was added thereto. After the mixture was neutralized with a 30% sodium hydroxide aqueous solution, the organic layer was separated from the water layer and the water layer was disposed of. The obtained organic layer was washed with water, and the water layer was separated and disposed of. The organic layer was concentrated under reduced pressure to obtain 83.1 g of the target compound (221.8 mmol, 86%). After stirring at the same temperature for reaction overnight were added reaction for 2 hours was added the organic layer was separated from the water layer The obtained organic layer was washed with water the water layer was separated The organic layer was concentrated under reduced pressure
