Procedure

First 5.6 g of potassium hydroxide in 12 ml of water and then 17.7 g (0.1 mol) of cyclohexylmethylbromide in 5 ml of dimethylsulphoxide were added dropwise to 29.3 g (0.1 mol) of 1-(4-chlorophenoxy)-2,2-dimethyl-4-(1,2,4-triazol-1-yl)-butan-3-one (prepared as described in Example 3) in 100 ml of dimethylsulphoxide at 20° C. The reaction mixture was subsequently stirred at room temperature for 15 hours, poured into 200 ml of water and extracted with 200 ml of methylene chloride. The organic phase was washed three times with 100 ml of water each time, dried over sodium sulphate and concentrated by distilling off the solvent. The residue was taken up in 100 ml of ether, whereupon the product crystallized out. 18.6 g (47% of theory) of 1-(4-chlorophenoxy)-5-cyclohexyl-2,2-dimethyl-4-(1,2,4-triazol-1-yl)-pentan-3-one of melting point 58°-60° C. were obtained.
