Reaction Steps
A mixture of 0.01 M 2,6-difluoronitrobenzene and 0.01 M hydrazine hydrate (99% strength) in 30 ml of THF was stirred overnight at RT (exothermic reaction) and the residue was brought to crystallization after distilling off the solvent by treating with diisopropyl ether. Crystalline substance, m.p.: 93-95° C.
