Versuchsvorschrift

DBU (914 mg, 6.0 mmol) was added to a solution of 3-(tert-Butyl-dimethyl-silanyloxy)-benzenethiol (1.00 g, 4.16 mmol) in bromo-chloro methane (5 ml) at room temperature. Stirring was continued for 2 hours and Et2O (50 ml) and 2M KHSO4 (30 ml) were added. The organic layer was separated, washed with 2M KHSO4 (30 ml) and brine (30 ml), dried (Na2SO4) and concentrated under reduced pressure. The resulting oil was analysed by 1H-NMR spectroscopy and was used without further purification. Yield: 1.01 g (84%).
