Procedure

2-Hydrazinyl-5,6,7,8,9,10-hexahydrocycloocta[b]pyridine (81 mg, 0.42 mmol) and (Z)-phenyl N′-cyano-N-(4-(4-methylpiperazin-1-yl)phenyl)carbamimidate (142 mg, 0.42 mmol) were suspended in isopropanol and subjected to microwave irradiation (150° C., 20 min). The crude product was purified by C-18 reversed phase HPLC to give 1-(5,6,7,8,9,10-hexahydrocycloocta[b]pyridin-2-yl)-N3-(4-(4-methylpiperazin-1-yl)phenyl)-1H-1,2,4-triazole-3,5-diamine, compound #23, as a white solid, 92 mg; 1H NMR (DMSO-d6, 300 MHz) 8.69 (s, 1H), 8.13 (s, 1H), 7.65 (d, 1H), 7.55 (s, 1H), 7.44 (d, 2H), 7.41 (d, 1H), 6.84 (d, 2H), 3.01 (m, 4H), 2.90 (m, 2H), 2.75 (m, 2H), 2.50 (m, 4H), 2.25 (s, 3H), 1.71 (m, 2H), 1.63 (m, 2H), 1.33 (m, 4H) ppm; MS (ES) 433.17 (M+H).
