Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Diethyl Ether | HCID 3283 | — |
| Reactant | Phenylhydrazine | HCID 7516 | — |
| Reactant | 2-benzoylnicotinic acid | HCID 824599 | — |
| Solvent | Toluene | HCID 1140 | — |
| Product | HCID 20078887 | HCID 20078887 | — |
Reaction Steps
A mixture of phenylhydrazine (5.0 g) and 2-benzoylnicotinic acid (3.25 g) in toluene was stirred at the reflux temperature for 7 hours. The solvent was then evaporated and the residue was purified by chromatography to give the crude product which, on trituration with diethyl ether, yielded the title compound as a yellow solid, 0.41 g, m.p. 173.5°-176.5° C.
