1-Amino-2-imidazolidinone (2.61 g, 0.026 mol) was dissolved in 200 ml of dichloromethane. The solution was cooled to 0° C. and 4.1 ml of triethylamine was added, followed by 7.5 g of 3,4-bis(acetyloxy)benzoyl chloride (0.029 mol). The mixture was stirred at 0° C. for 1 hour and at room temperature for an additional hour. The precipitate was filtered off to yield 8.3 g of 1-[[3,4-bis(acetyloxy)benzoyl]amino]-2-imidazolidinone.
