Reaction Steps

A mixture of 120 g of iron powder, 5 g of ammonium chloride, 2 liters of dioxane, and 800 ml of water was heated on a steam bath with stirring and after adding thereto 61 g of 2-(4-nitro-2-hydroxyphenyl)-1-formylhydrazine with stirring, the resultant mixture was refluxed for 40 minutes. Then, insoluble matters were distilled off the filtrate was concentrated under reduced pressure, and water was added to the residue. Crystals thus formed were collected by filtration and washed with acetonitrile to provide 40 g of the desired compound with a yield of 79%.
