Versuchsvorschrift

0.05 g of concentrated sulfuric acid was dropped in a mixture of 5.0 g of 1-diethoxymethyl-2-nitroiminoimidazolidine, 2.48 g of p-isopropylaniline and 2 ml of 1,3-dimethyl-2-imidazolidinone at 110° C., followed by agitation at the same temperature for 1 hour. The reaction mixture was poured into water, extracted with ethyl acetate, washed with water, dried and evaporated. Ether was added to the resultant oily residue and the resultant crystals were separated by filtration and dried to obtain 2.1 g of 1-(4-isopropylphenyliminomethyl)-2-nitroiminoimidazolidine.
