실험 절차

Methyl 4-nitro-1H-indazole-1-carboxylate 1.66 g, 7.5 mmol) and 10% Pd/C were combined in ethanol (20 mL) and exposed to a hydrogen atmosphere. The reaction mixture was heated at 80° C. for 20 minutes, allowed to cool to room temperature, and filtered through Celite. The filtrate was evaporated to provide title compound. 1H NMR (300 MHz, DMSO-d6) δ 6.1 (s, 2H), 6.41 (dd, 1H), 7.21 (m, 2H), 8.42 (s, 1H).
