Versuchsvorschrift

559 mg (3.10 mmol) of the compound from Example 77A and 0.26 ml (3.39 mmol) of trifluoroacetic acid were added to 500 mg (2.82 mmol) of the compound from Example 8A in 12 ml of dichloromethane. The reaction mixture was stirred at RT for 30 min and then diluted with dichloromethane, washed with saturated aqueous sodium bicarbonate solution and saturated aqueous sodium chloride solution, dried over sodium sulfate, filtered and concentrated. Purification of the crude product by preparative HPLC (mobile phase: acetonitrile/water gradient) resulted in 361 mg (38% of theory) of the title compound.
