Reaction Steps

To a solution of 1-bromo-2,5-difluoro-4-nitrobenzene (2.56 g, 0.011 mmol) in methanol (20 mL) was added a 25% sodium methoxide in methanol solution (2.5 mL). The mixture was stirred at room temperature for 1.5 hours. The reaction was then concentrated, re-dissolved in EtOAc and washed with water. The aqueous wash was back-extracted with EtOAc. The combined organic extracts were washed with brine, dried over sodium sulfate, filtered and concentrated to give 1-bromo-2-fluoro-5-methoxy-4-nitrobenzene (2.65 g, 99%).
