1H-Indazol-7-amine is a substituted-indazole, an inhibitor of nitric oxide synthases. | [Synthesis]
General procedure for the synthesis of 7-aminoindazole from 7-nitroindazole: 7-nitroindazole (100 mg, 0.67 mmol) was dissolved in methanol (6 mL) and Pd/C (10 wt%) was added to the reaction vessel. The reaction mixture was stirred in H2 atmosphere for 12 h at room temperature. After completion of the reaction, the mixture was filtered through a diatomaceous earth pad, the filtrates were combined and concentrated, and finally the product was purified by column chromatography. The yield was 95% (85 mg); 1H-NMR (DMSO-d6, 300 MHz) δ 12.58 (1H, br, NH), 7.91 (1H, s, Ar-H), 6.93 (1H, d, J = 9.0 Hz, Ar-H), 6.83 (1H, t, J = 9.0 Hz, Ar-H), 6.46 (1H, d, J = 6.0 Hz, Ar-H), 5.30 (2H, br, NH2). | [References]
