10 g (0.026 mol) of 1-(4-chlorophenoxy)-3-methyl-1-(1,2,4-triazol-1-yl)-3-trifluoromethylthio-butan-2-one (Example 1) were dissolved in 100 ml of methanol and 1 g (0.025 mol) of sodium borohydride was added in portions to the solution. The reaction mixture was further stirred at room temperature for 30 minutes and was thereafter introduced into water. The mixture was extracted with methylene chloride, and the organic phase was dried over sodium sulphate and concentrated in vacuo. The residue crystallized after a short time. 9.5 g (95% of theory) of 1-(4-chlorophenoxy)-3-methyl-1-(1,2,4-triazol-1-yl)-3-trifluoromethylthio-butan-2-ol of melting point 85°-87° C. were obtained.
