実験手順

3.63 g (16.4 mmol) of indium(III) chloride and 1.9 ml (24.6 mmol) of trifluoroacetic acid were added to 4.23 g (16.4 mmol) of the compound from Example 87A and 2.56 g (13.7 mmol) of the compound from Example 158A under argon in 300 ml of 1,2-dichloroethane, and the mixture was stirred under reflux for 4 h. 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 HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 3.16 g (49% of theory) of the title compound as mixture of diastereomers.
