Reaction Steps

In 10 ml of N,N-dimethylformamide was dissolved 1.5 g of 2-tert.-butyl-4-chloro-5-mercapto-3(2H)-pyridazinone, and thereto were added 1.2 g of anhydrous potassium carbonate and 1.0 g of α-chloro-o-xylene. The resulting mixture was heated to 80° to 110° C. under stirring for 2 hours. After allowed to cool to room temperature, the mixture was incorporated with 100 ml of water and then stirred. The precipitated solid was filtered off, washed with water, dried and recrystallized from ethanol to give white needle-like crystals having the following physical properties (yield: 72.7%):
