実験手順
A mixture of 5-(3-nitro-5-(trifluoromethyl)phenyl)-2H-tetrazole (220 mg, 0.849 mmol) in MeOH (10 mL) was added Pd/C (45.2 mg, 0.424 mmol) under N2. The mixture was stirred at 20° C. under a H2 atmosphere for 1 h. LCMS showed the reaction was finished. The mixture was filtrated, and the filtrate was concentrated to give 3-(2H-tetrazol-5-yl)-5-(trifluoromethyl)aniline (200 mg, 0.781 mmol, 92% yield): 1H NMR (400 MHz, METHANOL-d4) δ 7.96 (s, 1H), 7.71 (s, 1H), 7.32 (s, 1H). ES-LCMS (m/z) 230 (M+H).
