Procedure

A sealed tube with 3-chloro-4-fluorobenzonitrile (0.366 g, 2.4 mmol) and diethylamine (0.6 mL, 5.8 mmol) was heated to 100° C. for 8 hours. The reaction was allowed to cool to room temperature and water (5 mL) was added. The solution was extracted with dichloromethane (2×5 mL), dried over magnesium sulfate and concentrated in vacuo to afford 3-chloro-4-diethylaminobenzonitrile as an oil (0.38 g). This was reacted as described in Methods A-C (Examples 1-3) to provide the title compound. 1H NMR (CDCl3, 400 MHz) δ 8.89 (dd, 1H), 8.26 (d, 1H), 8.11 (ddd, 1H), 7.97 (dd, 2.2 Hz, 1H), 7.53 (d, 1H), 7.27 (dd, 1H), 7.15 (d, 1H), 3.86 (b, 2H), 3.20 (q, 4H), 3.03 (t, 2H), 1.91 (quint, 2H), 1.08 (t, 6H); MS (m/e) calculated for C21H26ClN5 383, found 384.3 (M+H).
