Procedure

In 30 ml of N,N-dimethylformamide were dissolved 2.2 g (0.01 mol) of 2-tert.-butyl-4-chloro-5-mercapto-3(2H)-pyridazinone and 3.5 g (0.0105 mol) of 4-(4'-trifluoromethylphenoxy) benzyl bromide, and thereto was added 2.1 g (0.02 mol) of anhydrous sodium carbonate to effect reaction at 85° to 90° C. for 4 hours. After the reaction, the reaction liquid was allowed to cool, poured into water and then extracted with benzene. The benzene layer was washed with 5% aqueous solution of sodium hydroxide and then with water, dried over anhydrous sodium sulfate and then freed of benzene by distillation under reduced pressure. The oily residue was incorporated with n-hexane and the precipitated crystals were filtered off to obtain white crystals (yield: 85.5%).
