Versuchsvorschrift

200 mg (0.78 mmol) of the compound from Example 76A with a purity of 75% and 152 mg (0.86 mmol) of the compound from Example 8A were introduced into 3.8 ml of dichloromethane at 0° C., 0.07 ml (0.94 mmol) of trifluoroacetic acid was added, and the mixture was stirred at 0° C. for 4 h. It was diluted with dichloromethane and added to saturated aqueous ammonium chloride solution, the phases were separated, the aqueous phase was extracted with dichloromethane, and the combined organic phases were dried over magnesium sulfate, filtered and concentrated. The residue was purified by preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 175 mg (64% of theory) of the title compound.
