실험 절차

To a solution of 180 mg of tert-butyl 3-(3-fluorophenyl)-5-nitro-1H-1-indazolecarboxylate in 10 ml tetrahydrofuran was added 100 mg of palladium (5%)-carbon, and the mixture was stirred at room temperature in an atmosphere of hydrogen gas at normal pressure for 3 hours. The reaction mixture was filtrated through Celite and the solvent was evaporated, to give 184 mg of the title compound as a light brown oil.
