Reaction Steps

To a solution of tert-butyl (2-(1-methyl-1H-indol-3-yl)ethyl)carbamate (4 g, 14.6 mmol) in DCM (30 mL) was added TFA (15 mL) at ˜0° C. to 5° C. The resulting reaction mixture was stirred at room temperature for 1 h. The reaction mixture was concentrated to give a crude title compound (2.5 g, crude) as yellow oil. MS (ESI) m/z 175.1 [M+H]+.
