Reaktionsschritte

A mixture of 5-Methyl-2-nitrophenol (7.7 g, 50 mmol), potassium carbonate (13.8 g, 0.1 mmol) and epibromohydrine (8.25 mL, 0.1 mmol) was dissolved in DMF (100 mL) and stirred 2-3 h at 100° C. under an atmosphere of nitrogen. The mixture was diluted with ether (0.5L) and extracted with water until pH=7. The organic phase was evaporated and the residue was purified by flash-chromatography on silica (DCM) to give the sub-title compound as a yellow solid (8.65 g, 83%).
