1H NMR spectrum showed two doublets around d=8.15ppm and d=7.31ppm, respectively. They were yielded from coupling of two neighboring H on benzene, both of which with 12 H. d=10.19 ppm indicates the chemical shift of H on primary amine, whereas d=7.31 ppm and 7.10ppm is the H shift on benzene. The presence of doublet at each shift indicated that contrapuntal nitro on benzene is substituted.
