実験手順
A solution of 5-Bromo-2-fluoro-pyridine (2.0 g, 11.4 mmol), [1,4]Diazepane (2.2 g, 22.8 mmol) in CH3CN (5.0 mL) was stirred at 50° C. for 3 hrs. Filter of the solid and the mother solution was brine, and concentrated in vacuo to give the title product (1.47 g, 51%) as a brown solid. ESI MS m/z 256 (M+H+); 1H NMR (400 MHz, CDCl3) δ 8.12 (d, J=7.0 Hz, 1H), 7.45 (dd, J=22.0, 6 Hz, 1H), 6.38 (d, J=22.0 Hz, 1H), 3.66 (m, 4H), 2.81 (t, J=15.0 Hz, 2H), 1.86 (m, 2H).
