Phenylhydrazones derived from 4-bromo-, 4-methoxy-, and 3-nitrobenzaldehydes react with allyl phenylcarbamate in the presence of N-chlorobenzenesulfonamide sodium salt to give the corresponding 3-aryl-1-phenyl-5-(phenylcarbamoyloxymethyl)-4,5-dihydro-1H-pyrazoles whose structure was confirmed by the IR and 1H and 13C NMR spectra.
