Procedure

From the reaction of 4-hydrazinobenzonitril and ethylbutyrylacetate, 4-(4,5-dihydro-5-oxo-3-propyl-1H-pyrazol-1-yl)-benzonitrile is obtained. Subsequent reaction with 2-ethylaniline yields 4-(4-(2-ethylanilinomethylene)-4,5-dihydro-5-oxo-3-propyl-1H-pyrazol-1-yl)-benzonitrile, Mp 196.7° C.
