Description of route of synthesis:
Dissolve 1- (2,4-dinitrophenyl) - N-methylethyl-1-imine in isopropanol, add palladium carbon catalyst, and introduce hydrogen gas for pressurized hydrogenation reduction; Two nitro groups are reduced to amino groups and undergo intramolecular condensation to form an indazole ring. After the reaction is completed, the palladium carbon is removed by filtration, the filtrate is concentrated, and then refined to obtain 2,3-dimethyl-6-amino-2H-indazole.
