Procedure

1-fluoro-2-nitrobenzene (1.85 mL, 175 mmol) and cyclopropanamine (2.43 mL, 35 mmol) were stirred in DMSO for 3 hours. Water was added (250 mL) and the mixture was extracted with ether (2×250 mL). The combined organic extracts were washed with brine, dried over sodium sulfate, filtered and evaporated to afford title compound 380 (3.1 g, 99%) as an orange oil. MS (m/z): 178.9 (M+H). 1H NMR (CDCl3) δ (ppm): 8.15 (dd, J=8.6, 1.6 Hz, 1H), 8.09 (s, 1H), 7.49-7.45 (m, 1H), 7.32 (dd, J=8.6, 1.4 Hz, 1H), 6.72-6.67 (m, 1H), 2.60-2.58 (m, 1H), 0.94-0.89 (m, 2H), 0.68-0.64 (m, 2H).
