Reaction Steps

A solution of 2-bromo-1-fluoro-4-nitrobenzene (0.94 g, 4.3 mmol) in N,N-dimethylformamide (10 mL) was treated with potassium carbonate (1.5 g, 11 mmol) followed by morpholine (0.56 mL, 6.4 mmol) and stirred at 20° C. for 3 h. The reaction mixture was diluted with sodium bicarbonate and extracted with ethyl acetate. The organic layer was separated, dried over anhydrous sodium sulfate, filtered, and evaporated to give the desired product (1.0 g, quantitative) which was used without further purification.
