How is 5-Bromo-1-phenyl-1H-pyrazole-4-carbonitrile (CAS: 76767-44-7) typically synthesized?

5-Bromo-1-phenyl-1H-pyrazole-4-carbonitrile is synthesized via a multi-step process that includes bromination and subsequent cyclization. Commonly, phenyl azide is brominated using N-bromosuccinimide (NBS) as the brominating agent. The reaction is typically carried out in a chlorinated solvent like dichloromethane under light or heat, followed by cyclization using a suitable base such as potassium carbonate in an aprotic solvent like dimethylformamide (DMF).
