実験手順

116 mg (0.53 mmol) of indium(III) chloride and 0.07 ml (0.86 mmol) of trifluoroacetic acid were added to 100 mg (0.48 mmol) of the compound from Example 86A and 120 mg (0.57 mmol) of the compound from Example 162A under argon in 5 ml of dichloromethane, and the mixture was stirred under reflux for 1 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 29.0 mg (15% of theory) of the title compound as mixture of diastereomers.
