1,3-Dimethyl-2-imidazolidinone → 1-(2-Phenylphenyliminomethyl)-2-nitroiminoimidazolidine

関与物質

反応手順

0.25 g of pyridine hydrochloride was added to a mixture of 5.0 g of 1-diethoxymethyl-2-nitroiminoimidazolidine, 3.64 g of o-aminobiphenyl and 3 ml of 1,3-dimethyl-2-imidazolidinone at 100° C., followed by agitation at the same temperature for 20 minutes. The reaction mixture was poured into water, extracted with ethyl ether, washed with water, dried and concentrated, followed by addition of ether to the resultant oily residue. The resulting crystals were collected by filtration and dried to give 3.2 g of 1-(2-phenylphenyliminomethyl)-2-nitroiminoimidazolidine.
