To a suspended mixture of 6-chloronicotinonitrile (7 g, 50.8 mmol) in EtOH (50 mL), was added NH2NH2 (10 g, 310.2 mmol). The mixture was stirred at room temperature for 10 min, and then 60° C. for 5 h. The mixture was cooled to room temperature. The solids were filtered out, washed with water and dried under high vacuum to give 6-hydrazinylnicotinonitrile (3.5 g). Compound 6 was prepared from 6-hydrazinylnicotinonitrile following the procedure of the synthesis of compound 4. 1H NMR (400 MHz, CDCl3-CD3OD 10:1) δ ppm 11.37 (s, 1H), 8.70 (t, J=1.2 Hz, 1 H), 8.14 (s, 1 H), 8.11(dd, J=1.04 and 9.52 Hz, 1 H), 7.96 (dd, J=1.12 and 9.52 Hz, 1 H), 7.61 (dd, J=1.52 and 9.48 Hz, 1 H), 7.38 (d, J=9.0 Hz, 1 H), 1.77 (m, 1 H), 1.06 (m, 2 H), 0.90 (m, 2H) ESI-MS:m/z 377.2 (M+H)+.
