反应详情

0.05 g of acetic acid was dropped in a mixture of 5.0 g of 1-diethoxymethyl-2-nitroiminoimidazolidine, 1.86 g of p-toluidine and 2 ml of 1,3-dimethyl-2-imidazolidinone at 120° C., followed by agitation at the same temperature for 3 hours. The reaction mixture was poured into water, extracted with ethyl acetate, washed with water, dried and condensed. Ether was added to the resultant oily residue and the resultant crystals were separated by filtration and dried to give 2.54 g of 1-(4-methylphenyliminomethyl)-2-nitroiminoimidazolidine.
