Procedure
From the reaction of 2-hydrazinobenzoic acid and ethylbutyrylacetate, 2-(4,5-dihydro- 5-oxo-3-propyl-1H-pyrazol-1-yl)-benzoic acid is obtained. Subsequent reaction with 2-ethylaniline yields 2-(4-(2-ethylanilinomethylene)-4,5-dihydro-5-oxo-3-propyl-1H-pyrazol-1-yl)-benzoic acid, Mp 126.9° C.
