Reaction Steps
Twenty nine grams 3-nitrobenzidine were dissolved in 330 ml ethanol containing 39 ml (36 grams) dimethyaniline. Thirty one grams ethylchloroformate were added to the ethanol solution in portions. The solution was then refluxed for 10 minutes after which water was added to precipitate the diurethane derivative. Forty one grams were obtained corresponding to a yield of 95%.
