Hydrazine hydrate (1:1) → HCID 9837507, compound

Participants

Reaction Steps

(4-Chlorophenyl)-(4-chloropyridin-3-yl)-methanone (3.88 g, 15.4 mmol) was dissolved in MeOH (20 mL) at room temperature and hydrazine hydrate (20 mL) was added. The reaction mixture was stirred for 3 h. The precipitate was filtered and purified by recrystallisation from PhMe/MeOH (˜4:1, ˜150 mL) to give 3-(4-chlorophenyl)-1H-pyrazolo[4,3-c]pyridine (1.16 g, 33.0%) as a yellow solid.
