1,3-Dimethyl-2-imidazolidinone → HCID 137226492, compound

Participants

Reaction Steps

0.05 g of boron trifluoride ether complex was added under ice-cooling conditions to a mixture of 5.0 g of 1-diethoxymethyl-2-nitroiminoimidazolidine, 3.47 g of o-aminobenzotrifluoride and 5 ml of 1,3-dimethyl-2-imidazolidinone. Immediately, the reaction mixture was poured into water, extracted with ethyl acetate, washed with water, dried and concentrated. Ether was added to the resultant oily residue and the resultant crystals were removed by filtration, followed by washing with hot ethyl acetate to give 3.43 g of 1-(2-trifluoromethylphenyliminomethyl)-2-nitroiminoimidazolidine.
