Versuchsvorschrift
1.01 g. (0.01 mol.) of 1-amino-2-imidazolidinone are dissolved in 20 ml. of anhydrous tetrahydrofuran and 20 ml. of a 1M solution of phosgene in toluene are added at 0°. The solution is stirred overnight at room temperature. The almost clear solution is filtered and evaporated to dryness. The 1-(chlorocarbonylamino)-2-oxoimidazolidine is obtained as an oily residue which is used without further purification.
