Versuchsvorschrift

4.34 g of 27 is dissolved in 189 ml of THF, cooled to −10° C., and 21.5 ml of methyllithium solution (1.6 M in diethyl ether) is added in drops under nitrogen. It is stirred for 2 hours at this temperature, and the reaction mixture is then poured into saturated ammonium chloride solution. After extraction with ethyl acetate, the organic phase is dried on sodium sulfate and concentrated by evaporation. The residue is chromatographed on silica gel with ethyl acetate/hexane, whereby 3.7 g of title compound 28 is obtained as a yellowish oil.
