0.05 g of trifluoroacetic acid was dropped in a mixture of 5.0 g of 1-diethoxymethyl-2-nitroiminoimidazolidine, 2.48 g of o-n-propylaniline and 2 ml of 1,3-dimethyl-2-imidazolidinone at 90° C., followed by agitation at the same temperature for 45 minutes. 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 give 1.6 g of 1-(2-n-propylphenyliminomethyl)-2-nitroiminoimidazolidine.
