Reaktionsschritte

tert-Butyl 2-(pyridin-2-yldisulfanyl)ethylcarbamate (1.06 g, 3.70 mmol) in 16 ml of EtAc was added 4.0 ml of HCl (conc.) at RT. The mixture was stirred at RT for 0.5 h, diluted with ethanol/toluene (6 ml, 1:1), evaporated and co-evaporated with ethanol/toluene (3×10 ml), crystallized with ethanol/EtAc/Hexane, filtered, and dried over a vaccum to afford 135 mg (88%) of the title compound. 1H NMR (CD3OD) 7.58 (m, 1H), 7.47 (m, 1H), 7.06 (m, 1H), 6.83 (m, 1H), 3.34 (m, 2H), 3.02 (m, 2H); 13C NMR 158.69, 149.07, 137.81, 122.48, 120.98, 39.52, 36.94; MS m/z+ 187.10 (M+H).
