Participants

Reaction Steps

0.05 g of boron trifluoride ether complex was added to a mixture of 46.4 g of 1-diethoxymethyl-2-nitroiminoimidazolidine, 27.8 g of 2-mercaptoaniline and 120 ml of 1.3-dimethyl-2-imidazolidinone under ice-cooling conditions, followed by agitation for 20 minutes. About 200 ml of ethyl acetate was added to the reaction mixture, and the resultant crystals were collected by filtration, washed with hexane and dried to give 61 g of 1-(2-methylmercaptophenyliminomethyl)-2-nitroiminoimidazolidine.
