A mixture of 2.0 g of 1-diethoxymethyl-2-nitroiminoimidazolidine, 0.92 g of m-toluidine, 5 ml of dimethoxyethane and 0.12 g of a boron trifluoride ether complex was heated under reflux for 1 hour. 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 1.1 g of 1-(3-methylphenyliminomethyl)-2-nitroiminoimidazolidine.
