Procedure

95.7 mg (0.43 mmol) of indium(III) chloride and 0.04 ml (0.49 mmol) of trifluoroacetic acid were added to 83.3 mg (0.40 mmol) of the compound from Example 167A and 100 mg (0.25 mmol) of the compound from Example 86A with a purity of 53% under argon in 5 ml of dichloromethane, and the mixture was heated under reflux for three days. It was concentrated and the residue was purified by preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 41.0 mg (33% of theory) of the title compound as mixture of diastereomers.
