Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Hydrazinobenzoic acid | HCID 12089 | — |
| Reactant | 3-Oxooctanoate | HCID 17804644 | — |
| Product | 4-(4,5-dihydro-5-oxo-3-propyl-1H-pyrazol-1-yl)-benzoic acid | HCID 19351340 | — |
Reaction Steps
From the reaction of 4-hydrazinobenzoic acid and ethylbutyrylacetate, 4-(4,5-dihydro-5-oxo-3-propyl-1H-pyrazol-1-yl)-benzoic acid is obtained. Subsequent reaction with 2-ethylaniline yields 4-(4-(2-ethylanilinomethylene)-4,5-dihydro-5-oxo-3-propyl-1H-pyrazol-1-yl)-benzoic acid, Mp 254.5° C.
