How is 3-(4-Bromophenyl)-5-methyl-1H-pyrazole (CAS: 145353-53-3) typically synthesized?

3-(4-Bromophenyl)-5-methyl-1H-pyrazole can be synthesized through a multistep process involving bromination of an aromatic ring followed by a condensation reaction. Commonly, bromobenzene is brominated using N-bromosuccinimide (NBS) or N-iodosuccinimide (NIS) in the presence of a radical initiator. Subsequently, the bromobenzene derivative is treated with a pyrazole ring precursor, such as 1,3-dimethylpyrazole, in an appropriate solvent like dichloromethane or toluene under reflux conditions.
