実験手順
471 mg (2.13 mmol) of indium(III) chloride and 0.25 ml (3.19 mmol) of trifluoroacetic acid were added to 400 mg (1.77 mmol) of the compound from Example 165A and 483 mg (2.13 mmol) of the compound from Example 87A under argon in 18 ml of dichloromethane, and the mixture was heated under reflux for 3 days. It was concentrated and the residue was taken up in ethyl acetate, washed with saturated aqueous sodium bicarbonate solution and saturated aqueous sodium chloride solution, dried over sodium 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) and another RP18 separation with acetonitrile/water 55:45 to result in 131 mg (17% of theory) of diastereomer 1 and 127 mg (17% of theory) of diastereomer 2 of the title compound.
