To a solution of 2-(4-chlorophenyl)-5-cyclopropyl-N-methyl-6-nitro-2H-indazole-3-carboxamide (127 mg, 0.34 mmol) in THF (2.5 mL) and MeOH (7.5 mL) was added Raney nickel (20 mg) and the reaction was stirred vigorously under an atmosphere of hydrogen at 60° C. for 2 h. The reaction mixture was diluted with MeOH (40 mL), filtered and then concentrated to dryness to give 6-amino-2-(4-chlorophenyl)-5-cyclopropyl-N-methyl-2H-indazole-3-carboxamide as a tan solid (97 mg, 83%).
