Reaktionsschritte

To a solution of 4-methanesulfinyl-phenol (1.52 g, 9.7 mmol) in DMF (30 ml) cesium carbonate (4.2 g, 12.9 mmol) was added, followed by addition of 5-bromo-2-nitro pyridine (1.75 g, 8.6 mmol) and the mixture was stirred at 50° C. over night. The suspension was filtered and evaporated+co-evaporated with toluene. The compound was purified by chromatography (0→10% EtOH in Methylene chloride) to give 1.5 g (56%) of 5-(4-Methanesulfinyl-phenoxy)-2-nitro-pyridine.
