Reaction Steps

1.4 g of 4-(1,1,2-trifluoro-2-trifluoromethoxy-ethoxy)-α-methyl-benzyl bromide (Example 2) and 1 g of 2-tert.-butyl-4-chloro-5-mercapto-3(2H)-pyridazinone are added to a suspension of 0.8 g of potassium carbonate in 10 cc of dimethylformamide. The resulting reaction mixture is stirred for 1 hour at room temperature, is diluted with ether, is washed with diluted HCl and brine; the washed solution is thoroughly dehydrated, the solvent is evaporated off and the so obtained raw reaction product is chromatographed on silica gel with 9/1 hexane/ethyl acetate. 0.58 g of pure product is obtained.
