Hydrazine hydrate (1:1) → HCID 22561707, compound

Participants

Reaction Steps

Hydrazine hydrate (0.4 mL, 12.7 mmol) was added to a solution of 2-fluoro-5-(1H-indol-4-yl)benzonitrile (1.2 g, 5.08 mmol) in n-butanol (25 mL). The mixture was heated to reflux under nitrogen for 3 days. The reaction was cooled to room temperature and the solvent was removed. The residue was purified on a silica gel column eluting with DCM: MeOH (95:5) to give 1.05 g (83%) of 5-(1H-indol-4-yl)-1H-indazol-3-ylamine as a white foam.
