Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Pyrazole | HCID 1048 | — |
| Reactant | 1-Bromo-4-nitrobenzene | HCID 11466 | — |
| Product | 1-(4-Nitrophenyl)-1H-pyrazole | HCID 605059 | — |
Reaction Steps
Following General Procedure A (90° C., 30 hours), 1H-pyrazole (205 mg, 3.0 mmol) is coupled with 1-bromo-4-nitrobenzene (404 mg, 2.0 mmol). The crude brown oil is purified by flash chromatography on silica gel (eluent: dichloromethane/hexanes=50/50) to provide 340 mg (90% isolated yield) of the desired product as a yellow solid.
