Procedure

tert-butyl 1-(3-(1,2,3,4-tetrahydro-2,8-dimethylpyrido[4,3-b]indol-5-yl)propanoyl)piperidin-4-ylcarbamate (50 mg) was stirred with trifluoroacetic acid (2 ml) in dichloromethane (2 ml) for 16 h at 25° C. to obtain 10 mg of 1-(4-aminopiperidin-1-yl)-3-(1,2,3,4-tetrahydro-2,8-dimethylpyrido[4,3-b]indol-5-yl)propan-1-one as di-TFA salt after purification by reverse-phase chromatography (C-18, 500 mm×50 mm, Mobile Phase A=0.05% TFA in water, B=0.05% TFA in acetonitrile, Gradient: 10% B to 80% B in 30 min, injection vol. 5 mL).
