実験手順

To a 250 mL round-bottom flask was added 5-bromo-2-fluorobenzonitrile (15.54 g, 77.7 mmol) and hydrazine (124 g, 3885 mmol). The reaction mixture was heated to 100° C. for 5 minutes. The hydrazine was then removed under reduced pressure to give 5-bromo-1H-indazol-3-amine (16.4 g, 99.5% yield). MS m/z: 213 (M+1).
