Reaktionsschritte

To solid potassium carbonate (11.59 g, 83.89 mmol) was added 4,4′-dithiodiphenol (7.00 g, 27.96 mmol), as a solid under argon, followed by N,N-dimethylformamide (130 ml). The stirred suspension was then heated to 80° C. over 2.25 h. Benzyl chloride (7.24 ml, 62.91 mmol) was then added over 2-3 minutes and the mixture stirred at 80° C. overnight. The mixture was then allowed to cool slowly to room temperature over the weekend. The resulting mixture was then poured into water (800 ml) and extracted with dichloromethane (3×250 ml). The organic extracts were combined and dried over sodium sulfate, filtered and evaporated to give a pale yellow solid which was tritureated with hot methanol (80 ml) which was allowed to cool slowly overnight to afford the title compound (D47). 1H-NMR (CDCl3) d 7.43-7.33 (14H, m), 6.90 (4H, dd, J 6.8 Hz, 2.0 Hz), 5.05 (4H, s).
