Versuchsvorschrift

1.62 g (7.31 mmol) of indium(III) chloride and 0.92 ml (12.0 mmol) of trifluoroacetic acid were added to 1.89 g (6.65 mmol) of the compound from Example 87A with a purity of 80% and 1.50 g (6.65 mmol) of the compound from Example 161A under argon in 75 ml of 1,2-dichloroethane, and the mixture was heated under reflux overnight. It was diluted with dichloromethane and washed with water and saturated aqueous sodium bicarbonate solution, dried over magnesium sulfate, filtered and concentrated. The residue was purified by preparative SFC HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 1.65 g (57% of theory) of the title compound as mixture of diastereomers.
