Procedure

2.6 ml (33.8 mmol) of trifluoroacetic acid were added to 7.07 g (28.2 mmol) of the compound from Example 150A and 5.00 g (28.2 mmol) of the compound from Example 8A in 620 ml of dichloromethane, and the mixture was stirred at RT for 2 h. It was concentrated and the residue was purified by flash chromatography on silica gel (mobile phase: toluene/ethyl acetate 98/2) and preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 960 mg (7% of theory) of the title compound.
