Komponenten

Versuchsvorschrift

40.5 g of 3-hydroxybenzotrifluoride, 18.0 g of α-butylene oxide and 1.0 g of lithium hydroxide monohydrate are heated in a bomb tube (pressure reactor) for 16 hours to 140° C. After cooling the reactor, the reaction mixture is dissolved in 200 ml of ethyl acetate and the organic phase is washed with water and then dried over sodium sulfate and concentrated. The desired product, 1-(3-trifluoromethylphenoxy)-2-butanol, is obtained in a yield of 54.0 g and in high purity. The product can be used in the subsequent reaction without further purification.
