实验过程

Diphenylcyanocarbonimidate (1.1 equiv) and 4-(2-(pyrrolidin-1-yl)ethoxy)aniline (1 equiv) were stirred in iso-propyl alcohol at ambient temperature overnight. The resulting white precipitate was filtered and washed with iso-propyl alcohol and dried to yield (Z)-phenyl N′-cyano-N-(4-(2-(pyrrolidin-1-yl)ethoxy)phenyl)carbamimidate. 3-Hydrazino-6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazine (82 mg, 0.36 mMol) and (Z)-phenyl N′-cyano-N-(4-(2-(pyrrolidin-1-yl)ethoxy)phenyl)carbamimidate (128 mg, 0.36 mMol) were suspended in isopropanol (3 mL) and subjected to microwave irradiation (150° C., 20 min). The precipitate which formed in the microwave vial was re-dissolved in hot isopropanol. The mixture was cooled to ambient temperature and then filtered to give 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-(4-(2-(pyrrolidin-1-yl)ethoxy)phenyl)-1H-1,2,4-triazole-3,5-diamine, compound #1, as a yellow solid, 23 mg. 1H NMR (CDCl3, 300 MHz) 7.90 (s, 1H), 7.83 (t, 1H), 7.43 (m, 3H), 7.29 (t, 1H), 6.93 (d, 1H), 6.83 (br s, 2H), 6.39 (s, 1H), 4.17 (m, 2H), 2.98 (m, 2H), 2.60-2.80 (m, 8H), 2.32 (m, 2H), 1.87 (m, 4H) ppm; MS (ES) 483.16 (M+H).
