Versuchsvorschrift

The compound obtained in Example 10 above (178 mg) was dissolved in 4N—HCl/dioxane (2 ml) and stirred at room temperature for 2.5 hours. To the reaction mixture, were added a saturated sodium hydrogen carbonate aq. solution and ethyl acetate and the organic layer was separated, washed with a saturated brine, dried over magnesium sulfate and concentrated in vacuo. The resulting residue was purified by column chromatography (silica gel; chloroform:methanol=1:0→9:1) to give the titled compound (157 mg). MS (m/z): 777 [M+H]+.
