To a mixture of 2.0 g (5.0 m mol) of 4,5-dibromo-2-(3,4-dichlorophenyl)-3(2H)-pyridazinone and 0.84 g (5.2 m mol) of 4-chloro-2-fluorobenzyl alcohol was added 80 ml of N,N-dimethylformamide. The resulting mixture was cooled with ice, incorporated with 0.4 g of potassium hydroxide and then stirred for one day. Then, the procedures in Synthesis Example 2 were repeated to give a crude product. The crude product was recrystallized from benzene to give 1.3 g of the intended compound.
