Procedure

23.6 parts by weight of acetyl chloride in 100 parts by volume of tetrahydrofurane were added dropwise over the course of 60 minutes to a suspension of 25.8 parts by weight of imidazol-2-one in 350 parts by volume of dry tetrahydrofurane. at 0° C. The mixture was stirred for 3 hours at room temperature, dry air was subsequently blown through the solution for some time, the solvent was then removed in vacuo and the residue was recrystallized from boiling nitromethane.
