Reaction Steps

100 g of powdered iron which has been reduced with hydrogen were added to 270 ml of water containing 27 ml of acetic acid and which had been previously heated to 80° C., and then 0.25 mole (66 g) of 3,5-dinitro-2,4-dimethoxychlorobenzene was added gradually, with stirring. Upon completion of the additions, the reaction mixture was maintained in a boiling water bath for 30 additional minutes. After cooling, the reaction mixture was centrifuged. The iron slurries which contained the expected product were taken up with acetone under vigorous mixing. Upon filtration of the iron slurries followed by washing with acetone, the expected product precipitated from the acetone filtrate upon addition of hydrochloric acid solution in ethanol. After thorough draining and washing, the expected product was recrystallized while hot from a hydrochloric acid and water mixture.
