such as hydroxyl and amine groups could be conveniently reduced with 3 molar equivalents of hydrazinehydrate in presence of Raneynickelcatalyst in ethanol/1,2-dichloroethane solvent mixture to give a product wherein one of the two nitro groups was reduced to the amino group. The yields of the partial reduction products are good. Under similar conditions alkoxyl substituents in the o,p-position to the
