Versuchsvorschrift

To a solution of N-(1-(3-(3,5-difluorophenyl)benzo[b]thiophen-2-yl)ethyl)-2-methylpropane-2-sulfinamide (392 mg, 0.996 mmol) in THF (7 mL) at rt was added HCl (1.0 mL, 11.85 mmol). The reaction was stirred at ambient temperature for 10 min, after which time LC-MS indicated no starting material remained. The reaction was poured into satd. aq. NaHCO3 and extracted two times with EtOAc. The combined organic extracts were stirred over MgSO4, filtered and concentrated under reduced pressure to give 1-(3-(3,5-difluorophenyl)benzo[b]thiophen-2-yl)ethanamine as a colorless oil: 1H NMR (500 MHz, CDCl3) δ 1.35 (d, J=6.7 Hz, 3H), 1.60 (br. s., 2H), 4.39 (q, J=6.6 Hz, 1H), 6.73-6.86 (m, 3H), 7.19-7.24 (m, 2H), 7.30-7.36 (m, 1H), 7.71-7.77 (m, 1H); LC-MS (ESI)] m/z 273.0 [M+H]+.
