Methods: 2ethyl aniline was used as starting material of the synthesis and was processed by acetic anhydride acylation, strong nitric acid nitraction at low temperature, and desacyl synthesis to produce 2ethyl5nitro aniline. The product was then synthesized to 3methyl6nitro1Hindazole by using ringclosing reaction in the presence of NaNO2, and then ethylated to obtain 2,3diethyl6 nitro2Hindazole. The latter compound was then reduced by SnCl2/Hcl to get target compound 2,3diethyl6nitro2Hindazole.
