Versuchsvorschrift

2,4-Difluoronitrobenzene (1.00 g, 6.29 mmol), potassium fluoride (0.365 g, 6.29 mmol), potassium carbonate (0.869 g, 6.29 mmol), and 40% methylamine in water (0.58 mL, 7.5 mmol) were added to a vial and heated in a microwave at 90° C. for 10 min. The reaction was then diluted with dichloromethane, washed with water and brine, dried over magnesium sulfate, and concentrated to provide the title compound: 1H NMR (500 MHz, CDCl3) δ 8.22 (dd, J=9.4, 6.1 Hz, 1 H), 8.16 (br s, 1 H), 6.48 (dd, J=11.5, 2.6 Hz, 1 H), 6.40-6.36 (m, 1 H), 3.01 (d, J=5.0 Hz, 3 H).
