In an analogous manner to the procedure of Example 1, 172 mg (0.507 mmol) of 5-(2,6-dimethyl-4-nitrophenoxy)-3-isobutyl-1H-indazole are reacted with 25 mg of palladium/carbon (10%) in 15 ml of ethanol under hydrogen in the course of 3 h to give 100 mg (64%) of 5-(4-amino-2,6-dimethylphenoxy)-3-isobutyl-1H-indazole.
