5.5 g of 1-p-phenylphenoxy-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-ol is dissolved in 25 ml of THF. 2.9 g of triethylchlorosilane and 0.2 g of 4-dimethylaminopyridine are added under a nitrogen blanket. The mixture is heated to 45° C., and 3.3 g of triethylamine is added in portions. After the mixture has been stirred for 14 hours at from 40° to 50° C. it is cooled to room temperature, undissolved matter is filtered off, and the filtrate is concentrated. The product is further purified either by adding petroleum ether, followed by filtration and concentration, or by gel filtration (SiO2, CHCl3). There is obtained 3 g of 1-p-phenylphenoxy-3,3-dimethyl-2-triethylsiloxy-1-(1,2,4-triazol-1-yl)-butane.
