Reaction Steps
From the reaction of N-tert.-butyl-4-hydrazinobenzenesulfonamide and ethylbutyrylacetate, N-tert.-Butyl-4-(4,5-dihydro-3-propyl-5-oxo-1H-pyrazol-1-yl)-benzenesulfonamide is obtained. Subsequent reaction with 2-ethoxyaniline yields N-tert-butyl-4-(4-(2-ethoxyanilinomethylen)-4,5-dihydro-3-propyl-5-oxo-1H-pyrazol-1-yl)-benzenesulfonamide, Mp: 254° C.
