General procedure for the synthesis of 1-acetyl-2-imidazolidinone from 2-imidazolidinone and acetic anhydride: 5.18 g (60.2 mmol) of 2-imidazolidinone and 50 mL of acetic anhydride were added to a 100 mL round-bottom flask. The mixture was placed in an oil bath and the reaction was stirred at 150 °C for 1 hour. Upon completion of the reaction, the mixture was cooled to room temperature and filtered to collect the precipitated solid. The solid was washed with a small amount of cold ethanol to give a final 4.94 g (yield: 64.1%) of colorless solid 1-acetyl-2-imidazolidinone.

5.18 g (60.2 mmol) of 2-imidazolidone and 50 mL of acetic anhydride were added to a 100 mL recovery flask, and the mixture was stirred at an oil bath temperature of 150 ° C. for 1 hour. After cooling to room temperature, the precipitated solid was collected by filtration and washed with a small amount of cold ethanol to obtain 4.94 g (yield: 64.1%) of colorless solid 1-acetyl-2-imidazolidone.
