Trifluoroacetic acid → 3-[1-Cyclopropyl-1-(4-methylphenyl)ethyl]-7-[(methylsulfanyl)methyl]-1H-indole

Participants

Reaction Steps

0.23 ml (3.00 mmol) of trifluoroacetic acid was added to 885 mg (4.99 mmol) of the compound from Example 8A and 440 mg (2.50 mmol) of the compound from Example 137A in 44 ml of dichloromethane, and the mixture was stirred at RT overnight. The reaction mixture was concentrated in a rotary evaporator. The residue was purified by preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 87.4 mg (10% of theory) of the title compound as mixture of diastereomers.
