| Reactant | Ethyl Acetoacetate | HCID 8868 | — |
| Reactant | 3-Hydrazinylbenzonitrile | HCID 1488145 | — |
| Product | 3-(4,5-Dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl)benzonitrile | HCID 19351257 | — |
Reaction Steps
From the reaction of 3-hydrazinobenzonitrile and ethylacetoacetate, 3-(4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl)-benzonitrile is obtained. Subsequent reaction with 2-ethylaniline yields 3-(4-(2-ethylanilinomethylene)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl)-benzonitrile, Mp 210.8° C.
