実験手順
17.8 g of 1-(2,4,6-trichlorophenyl)-3-{3-[2-(2,4-di-tert-amylphenoxy)butyramido]benzamido}-4-bromo-5-oxo-2-pyrazoline and 10 g of 4-acetamidopyrazole were well mixed in a mortar and heated at 100° C. for 2 hours. To the reaction mixture, 200 cc of ethyl acetate was added and the mixture was washed several times with water. The ethyl acetate layer was dried with anhydrous sodium sulfate and concentrated. Upon crystallization of the residue from a solvent mixture of acetonitrile and ethyl acetate, 12.1 g of Coupler (1) was obtained. The melting point of the coupler was 135° to 141° C.
