Reaction Conditions

Reaction Steps

5.0 g of 2-nitroiminoimidazolidine and 4.5 g of propionaldehyde were dissolved in 25 ml of N,N-dimethylformamide, and 4.0 g of phosphorus pentoxide was added thereto with cooling with ice over a period of 20 minutes and thereafter stirred for 10 minutes at 10° C. 20 ml of water and 20 ml of ethyl acetate were added to the reaction mixture, and the crystals thus precipitated out were filtrated and dried to give 4.3 g of 1-(1-propenyl)-2-nitroiminoimidazolidine.
