Versuchsvorschrift

tert-Butyl 6-{2-[(phenylsulfonyl)amino]ethyl}-1,4,5,6-tetrahydroazepino[4,5-b]indole-3(2H)-carboxylate (0.0430 g, 0.0916 mmol) was dissolved in CH2Cl2 (2 mL) at rt. CF3CO2H (1 mL) was added, then the reaction mixture was stirred for 2 h. The reaction mixture was concentrated and the residue was taken up in EtOAc (2 mL). HCl in Et2O (1N) (2 mL) was added and the precipitated salt was collected by filtration. N-[2-(2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)ethyl]benzenesulfonamide hydrochloride (0.0335 g) was obtained in 90% yield. 1H NMR (300 MHz, CD3OD) δ 3.16, 3.19-3.23, 3.37-3.41, 3.44-3.47, 3.53-3.57, 4.34, 7.08, 7.15, 7.32, 7.49, 7.52, 7.61, 7.77; MS (ESI+) for C20H23N3O2S m/z 370.1 (M+H)+.
