Following the general procedure 2B, 733 mg (4.42 mmol) of 4-fluro-3-nitrobenzonitrile in 80% aqueous ethanol (20 mL) was added cyclopropylmethylamine (377 mg, 5.3 mmol) at room temperature. The mixture was stirred at 60° C. for 3 h before work-up. The crude product (920 mg, 96%) was used for the next step without further purification. 1H NMR (400 MHz, CDCl3): δ 8.52 (s, 1H), 8.51–8.47 (br, 1H), 7.59 (d, J=8.4 Hz, 1H), 6.90 (d, J=8.4 Hz, 1H), 3.22–3.20 (m, 2H), 1.25–1.15 (m, 1H), 0.73–0.59 (m, 2H), 0.42–0.35 (m, 2H). MS (ESI) [2×(M+H)+]: 436.
