실험 절차

600 mg (2.25 mmol) of the compound from Example 91A and 0.21 ml (2.70 mmol) of trifluoroacetic acid were added to 399 mg (2.25 mmol) of the compound from Example 8A in 4 ml of dichloromethane. The reaction mixture was stirred at RT for 30 min. Purification of the crude product by preparative HPLC (mobile phase: acetonitrile/water gradient) resulted in 576 mg (60% of theory) of the title compound.
