실험 절차

1.05 g (4.75 mmol) of indium(III) chloride and 0.55 ml (7.12 mmol) of trifluoroacetic acid were added to 954 mg (3.96 mmol) of the compound from Example 160A and 1.02 g (4.75 mmol) of the compound from Example 86A in 60 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 HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 197 mg (12% of theory) of the title compound as mixture of diastereomers.
