Reaction Steps

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 cyclopropylamine (0.52 mL, 7.54 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: LCMS m/z 196.95 [M+H]+; 1H NMR (500 MHz, CDCl3) δ 8.20 (dd, J=9.5, 6.0 Hz, 2 H), 6.95 (dd, J=11.4, 2.6 Hz, 1 H), 6.43-6.39 (m, 1 H), 2.58-2.53 (m, 1 H), 0.96-0.92 (m, 2 H), 0.69-0.66 (m, 2 H).
