Procedure

A suspension of 15.5 g of powdered zinc and 0.6 g of ammonium chloride is heated to reflux. After the source of heat has been removed, 0.02 mole (3.6 g) of 2,6-dimethyl-4-nitro-N-methylaniline is added so as to maintain reflux. At the end of the addition, the reaction mixture is filtered boiling into a solution of 0.05 mole of hydrochloric acid in 14 ml of absolute ethanol; the dihydrochloride crystallises from the filtrate. After recrystallisation from an alcohol-water mixture, a white product is obtained:
