Versuchsvorschrift

5.5 g of the product of step c) and 50 ml aqueous trifluoroacetic acid (70%) are stirred at room temperature 20 hours. To the mixture are added CH2CL2 and dropwise aqueous KHCO3 solution. The organic phase is dried (Na2SO4) and evaporated. The residue is taken up in diethyl ether, filtered and evaporated to dryness, to give the heading compound as an oil.
