Participants

Reaction Steps

104 mg (0.48 mmol) of the compound from Example 156A and 0.04 ml (0.57 mmol) of trifluoroacetic acid were added to 100 mg (0.48 mmol) of the compound from Example 86A in 4 ml of dichloromethane. The reaction mixture was stirred at RT for 45 min, the solvent was removed in vacuo, and the crude product was then purified by preparative HPLC (mobile phase: acetonitrile/water gradient). 100 mg (51% of theory) of the title compound were obtained.
