実験手順

A mixture comprising 4.0 g of 2-nitroiminoimidazolidine, 20 ml of 1,3-dimethyl-2imidazolidine, 7.5 g of phosphorus oxychloride and 2.7 g of propionaldehyde was stirred for 30 minutes at room temperature. The reaction mixture was poured into water, extracted with ethyl acetate, washed with water, dried (with anhydrous MgSO4) and concentrated. The crystals thus precipitated out were sludged with ethyl acetate, filtrated and dried to give 1.7 g of 1-(1-propenyl)-2-nitroiminoimidazolidine.
