How is Benzyl {(1S)-2-[(2,5-dioxo-1-pyrrolidinyl)oxy]-2-oxo-1-phenylethyl}carbamate (CAS: 146118-22-1) typically synthesized?

Benzyl {(1S)-2-[(2,5-dioxo-1-pyrrolidinyl)oxy]-2-oxo-1-phenylethyl}carbamate is typically synthesized through a multi-step process involving the condensation of a benzylamine with a pyrrolidone derivative. The reaction involves the use of a base catalyst such as potassium carbonate and is carried out in an organic solvent like dimethylformamide (DMF). The overall yield and selectivity of the reaction can be enhanced by optimizing reaction conditions such as temperature and time.
