Versuchsvorschrift

A suspension of 30 g of the product of Step A and 180 ml of ethanol was heated to reflux and 30 ml of hydrazine hydrate were added thereto. The mixture was refluxed for 15 minutes and then 180 ml of distilled water were added thereto. The mixture was cooled to 10° C. and was vacuum filtered. The product was washed with water and dried to obtain 19 g of 4-dimethylamino-N'-(4-nitrophenyl)-benzenecarbohydrazonamide melting at 174° C.
