Versuchsvorschrift

11.2 g of 5 is dissolved in 150 ml of toluene and cooled under nitrogen to 0° C. 125 ml of DIBAH solution (1.2 M in toluene) is now slowly added in drops and stirred for 2 more hours. Then, 1.25 ml of isopropanol and 25 ml of water are added in drops and stirred overnight. The precipitate is filtered off, the filtrate is concentrated by evaporation and chromatographed on silica gel with ethyl acetate/hexane, whereby 9.1 of title compound 6 accumulates as a colorless oil.
