Procedure

Sodium hydroxide 0.7 g was dissolved in 15 ml of water, and thereto were added 100 ml of benzene, 3.3 g of 2-tert.-butyl-4,5-dichloro-3(2H)-pyridazinone and 0.15 g of triethylbenzylammonium chloride. The resulting solution was incorporated with 2.4 g of 4-chlorobenzyl mercaptan at room temperature and then stirred for 15 hours. After completion of the reaction, only the organic layer was separated therefrom, washed with a 5% aqueous solution of sodium hydroxide and then with water, and dried over anhydrous sodium sulfate. Solvent was distilled away therefrom under reduced pressure. The resulting oily residue was incorporated with hexane to give crystals. The crystals were filtered off to obtain 3.3 g of the intended compound (yield: 64%).
