Reaction Steps
25 mg of palladium/carbon (10%) are suspended in a solution of 175 mg (0.538 mmol) of 5-(2,6-dimethyl-4-nitrophenoxy)-3-isopropyl-1H-indazole in 10 ml of ethanol. The mixture is shaken under a hydrogen atmosphere at 3 bar for 4 h, then filtered off through kieselguhr, the filtrate is concentrated in vacuo and the residue is purified on silica gel (cyclohexane/ethyl acetate 2:1). 50 mg (31%) of 5-(4-amino-2,6-dimethylphenoxy)-3-isopropyl-1H-indazole are obtained.
