The reaction of Step 2 is specifically performed as follows. The Pd/C of 5-15%, and preferably 10%, relative to the mass of the substrate, is added as the catalyst to the 2,2′,6,6′-tetranitrobiphenyl. The hydrogen gas of 5-20 atm, and preferably 10 atm, is added to the autoclave. Upon completion of the reaction, the solid is filtered off, and the filtrate is concentrated, to afford the 2,2′,6,6′-tetraminobiphenyl.
