실험 절차

15 g of 3-(2-chloro-5-tetradecanamidoanilino)-1-(2,4,6-trichlorophenyl)-2-pyrazolin-5-one and 5.4 g of 1-(3-carboxyphenyl)-5-mercaptotetrazole were dissolved in 100 ml of DMF and to the solution was added dropwise at room temperature 20 ml of a DMF solution containing 4.9 g of N-bromosuccinimide. After stirring for 30 minutes, 500 ml of water was added to the mixture which was extracted with ethyl acetate. The ethyl acetate was distilled off under reduced pressure and the residue was crystallized from a solvent mixture of ethyl acetate and acetonitrile to obtain 14 g of 3-(2-chloro-5-tetradecanamidoanilino)-1-(2,4,6-trichlorophenyl)-4-[1-(3-carboxyphenyl)-5-tetrazolylthio]-2-pyrazolin-5-one. Yield: 68%. Melting Point: 155° to 165° C.
