Trifluoroacetic acid → (1-(2-Aminoethyl)-1H-indol-5-yl)(4-(4-chlorophenoxy)piperidin-1-yl)methanone

Participants

Reaction Steps

A mixture of tert-butyl (2-(5-(4-(4-chlorophenoxy)piperidine-1-carbonyl)-1H-indol-1-yl)ethyl)carbamate (112 mg, 0.23 mmol, Step-1), trifluoroacetic acid (1.5 mL), and dichloromethane (1.5 mL) was stirred at room temperature for 1 hour. After concentration in vacuo, the residue was purified by a strong cation exchange cartridge (BondElute(registered trademark) SCX) to give 83 mg (83% yield) of the title compound as yellow oil. 13 mg of this material was further purified by preparative LC-MS to give 6.6 mg (51% yield) of the title compound.
