実験手順
1-Bromo-2-fluoro-4-methyl-5-nitrobenzene (1.0 g, 4.3 mmol) [Aldrich] was stirred in N,N-dimethylformamide (10 mL) with potassium carbonate (1.5 g, 11.0 mmol), and morpholine (0.56 mL, 6.4 mmol) was added. The mixture was stirred for 3 hours and diluted with saturated sodium bicarbonate solution. Extraction with ethyl acetate gave the desired compound (1.0 g, 77%). LCMS for C11H14BrN2O3 (M+H)+: m/z=301.0.
