Trifluoroacetic acid → 3-[(2-Chloro-4-methylphenyl)(cyclopropyl)methyl]-7-[(methylsulfonyl)methyl]-1H-indole

Participants

Reaction Steps

135 mg (0.61 mmol) of indium(III) chloride and 0.07 ml (0.92 mmol) of trifluoroacetic acid were added to 132 mg (0.61 mmol) of the compound from Example 86A and 100 mg (0.51 mmol) of the compound from Example 152A in 5 ml of dichloromethane, and the mixture was stirred at RT overnight. It was concentrated and 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.
