Reaction Steps
A solution of 31 g of potassium ethoxylate, 51 ml of ethyl oxalate and 0.25 l of dimethylformamide is added to a solution of methyl N-(2,3-dimethyl-5-nitrophenyl)formimidate (52 g) in 0.37 l of dimethylformamide. The temperature of the mixture is raised to 40° C. for 3 hours. The precipitate is filtered off and washed with water. The precipitate is taken up in hot isopropyl ether and then filtration is carried out.
