Reaction Steps
From the reaction of N,N-diethyl-4-hydrazinobenzenesulfonamide and ethylacetoacetate gives N,N diethyl-4-(4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl)-benzenesulfonamide. Subsequent reaction wvith 2-ethoxyaniline yields N,N-diethyl4-(4,5-dihydro-4-(2-ethoxyanilinomethylene)-3-methyl-5-oxo-1H-pyrazol-1-yl)-benzenesulfonamide, Mp: 170° C.
