The title compound was synthesized from ketone 5e (Vlahakis, J. Z.; Kinobe, R. T.; Bowers, R. J.; Brien, J. F.; Nakatsu, K.; Szarek, W. A. Bioorg. Med. Chem. Lett. 2005, 15, 1457-1461) by the procedure employed for the synthesis of QC-15, except using 1,2-ethanedithiol instead of ethylene glycol, to afford a beige solid in 32% yield after recrystallization (2-propanol): mp 204-205° C.; Rf=0.21 (EtOAc); 1H NMR (400 MHz, CD3OD): δ 2.17-2.25 (m, 2H), 2.94-3.06 (m, 4H), 3.28-3.38 (m, 2H), 4.65 (s, 2H), 7.21 (d, 8.4 Hz, 2H), 7.28 (d, J=8.4 Hz, 2H), 7.56 (s, 1H), 7.81 (s, 1H), 9.11 (s, 1H); 13C NMR (100 MHz, D2O): δ 32.6, 41.6, 43.4, 59.8, 71.2, 119.9, 125.5, 129.6, 131.1, 133.0, 138.2, 141.3; HRMS (ES) [M−Cl]+ Calcd. for C15H18ClN2S2: 325.0600. Found: 325.0587.
