Versuchsvorschrift

A mixture of 6.35 g (0.050 mole) of 1,3-dimethyl-2-iminoimidazolidin-4-one, 7.85 g (0.050 mole) of 3-chlorophenylisocyanate and 75 ml of dry tetrahydrofuran is stirred at room temperature for 4 hours. The solution is evaporated in vacuo and the residue is crystallized from acetonitrile. Two recrystallizations from acetonitrile - ether gives pure product, 1-(3-chlorophenyl)-3-(1,3-dimethyl-4-oxo-2-imidazolidinylidene)urea, m.p. 134°-137°C.
