Two synthetic methods have been developed for the synthesis of 3,5-dichloro-2,4,6-trinitrobenzenamine.In the first process,3,5-dichlorobenzenamine was selected as precursor,followed by N-protection,nitration,and hydrolysis. In another process,1,3,5-trichloro-2,4,6-tri-nitrobenzene(TCTNB) reacted with 2-amino-2-methylpropane and then trifluoroacetic acid to deprotect.The condensation between 3,5-dichloro-2,4,6-trinitrobenzenamine and methylamine gave 3,5-dimethylamino-2,4,6-trinitrobenzenamine in 85% yield which can be converted to the nitrate of 3,5-dimethylnitramino-2,4,6-trinitrobenzenamine in 70% yield. The structure of the product was confirmed by 1H NMR,MS,IR and elemental analysis. The results of selective of TCTNB under different conditions were discussed.The optimized conditions are:n(TCTNB):n(t-butylamine)=1:2,CuO as catalyst,KHCO3 as base.
